Spring rebounders or bungee rebounders are not better than the other. The best rebounder is the model that fit YOUR bouncing style and needs. I wrote this page to  help you decide on which rebounder is best for you without listening to a sales person say one is better than the other.
Lymphatic flow becomes more active on spring rebounders that use less energy while the bungees give more free bounces. Spring rebounders can move up to 15 times as much lymph without jumping higher than just barely out of the mat. Bungees take more energy to jump because the bungee cords
have to stretch far to harness G force.

I do not recommend the bungee rebounder for lymphatic drainage unless you want minimal drainage which the smallest mats provide but still nothing like a spring rebounder. The smaller mats give more bounces per minute so the long air time doesn't disrupt the negative pressure in the lymph valves by having the valves closed to long while you are in the air too long on a bungee rebounder.

The less time the valves stay shut the more lymph it can push. If jumping high like on a bungee rebounder the waste is not dislodging and replenishing the cells with clean lymph. The more flushes per minute a rebounder gives the more waste can be removed. The bungee can give a high amount of bounces with barely leaving the mat but the G force is negligible. No where close to 3 G forces.

The Needak has the softest bounce when doing the Health bounce but depending on a persons weight it can be at 4x, 5x or as far as 15x depending on the weight of a person. 

Note: As long as you are getting the right number of bounces per minute that I've found standard for your current weight, you should be getting 3 G force. The Cellerciser based on peoples weight gives the 2nd most bounces per minute after the top lymphatic rebounder, the New Zealand Lymphaciser.

I can't give the exact lymphatic rate but if 15x is the highest, the lymphaciser sets the bar. Once you feel what a Lymphaciser is like, then you can gauge how G force from other rebounders feel based on the bounces you are getting per minute. This is also based on how high you jump unless the rebounder adjusts to your weight like the Cellerciser. When the rebounder is too soft, not only you get less bounces per minute but the G force is less. Try the Needak and you will feel what I mean.

The nutrients go back into the cells during the air time, when the body is weightless. This is when the pressure on the body is at its lowest. If the G force or force was not strong enough to move the toxic fluid out, then as far as I'm concerned the air time is just a waste of time. On bungees that are too soft people think they are moving lymph when in actuality they are not. If the toxic fluid is still in the cell, then there is no room to replace it with clear lymph. There is no room.
Keep in mind how the bungee and the spring's responsiveness differ. Just like a Cellerciser bounce has a totally different bounce than a short barrel ReboundAir spring. The bungee responds differently to different weights unless you get the Jumpsport cords that can be adjusted for different family members of different weights. You don't have to buy 2 bungee rebounders with different tensions. With the bungees you have to get the size and cord strength just right or the bounce will feel off. If the bounce is too soft I have to use more calf muscles and after about 5 minutes I feel like I just did a whole calve workout and cannot continue my workout. A stronger cord will compensate for this but will give me less deeper bounces.

Note: on a bungee rebounder, I will rarely see someone landing on their heels first, almost always the toes. You can move lymph by working out the muscles but for the Health bounce, landing on your heels is what can move up to 15x as much lymph that just working out. I urge people to know this before buying a rebounder.

If using a rebounder that has a soft bounce (Needak soft bounce) or soft tension bungee, to avoid burning out your calves it is helpful to have the bar or if you have strong arms you can use your arms and move them up and down to help you bounce up and down.

Many rebounders are too soft and too firm and you have to land on your toes first to avoid the pressure against the knees. Very firm rebounders are painful to do the heel to toe bounce. Rebounders that are too soft might cause you to use more of your leg muscles or arms to get a enough bounce which interferes with absorbing the G force. For those that are trying to detox and want to gain a healthier body function, it is important to know what you are doing and how to bounce the right way to do it. (see my rebounding for detox page)
A balanced rebounder suited for someones weight should give a person around 90 to about 120 bounces each minute. At the lower end, a rebounder will give the body 3 G forces 5,400 times up to 7,200 times.  That's up to 7,200 jumps in one hour. (120x60)
Using the balance bar can help greatly to stay in that sweet spot that gives you the most bounces per minute.

Bungee cord rebounders came out in the 70s but now they are back. The bungee rebounder are the cheapest rebounders (if you buy them in the countries they are made) but can be marked up almost triple depending on who you buy from. The Half fold Cellercisers sold in Italy or Australia cost over 600 dollars while they are only 365 here in the states. 
Still can't decide over a bungee and a spring rebounder?
The bungees get rid of almost 100% of the ballistic impact. The jarring rebounders get rid of around 5/8ths of the impact. The Cellerciser claims to rid 7/8ths of the ballistic impact. With the bungee the ballistic impact is negligible enough to make it feel like real backyard trampoline with those 12 inch springs. They are great for cardio, dancing and all the movements you see people doing in the youtube videos. I have never seen a video of someone doing the health bounce. It really bugs me when certain people who don't know rebounding talk about the health bounce and they are trying to sell a bungee rebounder. The "buzz word" Health Bounce should only be used when talking about lymphatic rebounders that. If someone has lymphatic issues and they buy a bungee thinking it going to help them, its just not fair to them. This is no time for trial and error when someones health is concerned.
If using a rebounder for cardio and toning only, the bungee is the best way to go. If bouncing for detox and lymphatic drainage, the spring rebounders high repetition allows for the most lymph drainage per minute. It is not just about doing it quicker. Many people say they are going to be on it for an hour and don't mind half as many bounces if just rebounding for 40 minutes instead of 20 minutes. It is the pause while being airborne too long that cancels out the negative pressure. Bouncing on a bungee even if you have to bounce 3 times as high to get 3 G forces as doing the Health bounce is still not the same. I hope people don't think just doing 120 bounces in per minute on a spring or doing 120 bounces on a bungee that takes more than a minute is the same thing.

I bring my rebounder in the steam room and sauna at my gym and bounce. All the dudes usually leave the steam room as they feel uncomfortable with me bouncing naked. I tried to wear a robe but thats even more awkward seeing a guy bouncing in a robe with naked men all around. Everyone seems to have a problem with me every where I bring my rebounder. They even complain when I'm doing deep belly breathing or when I dry brush my skin in the sauna. They are offended meanwhile they are the ones with teh sluggish lymph system with fibrin all over their body. Whats offensive to me is the smelly people in the sauna that are smelling like pigs walking around with toenail fungess barefoot.

Cardio Bounce - This is where you jump in the sweet spot where you can't be thrown off by the firmer edge and a softer center.
This is the type of bouncing when jogging in place where I get my knees up as high as I can while always keeping only one foot on the mat. It's always nice to do Health Bouncing before doing this to warm up. A bungee rebounder makes it hard unless its the strongest tension and its a small mat.
If the bounce is too jarring. Like on a ReboundAir or Urban, your legs can get locked when you run in place. With a rebounder that is suitable for your weight and jumping style, this accidentally leg locking rarely happens. The Cellerciser, Needak, and Lympholine (not Lymphaciser) adjusts to your weight and is the only rebounder that I have never heard of this happening. The Lymphaciser should never give you leg-lock if you don't jump outside the mat.
It's Time To Choose!
Bungee or Spring
I finally now can do the Health Bounce. I could not do it even if I wanted to on my original rebounder. It was way too soft and I couldn't get 3 G forces unless I jumped out of the mat. It was not the Needak or Cellerciser.
How to choose a bungee cord rebounder.
(unless you want to buy a used rebounder and build one yourself, costs only 50 bucks to build one.
Its real easy to do. You go to Home depot and buy bungee cords and buy some pliers and some fasteners. You weight each cords so they are all the same and the same length. (You can buy higher end 6mm cord on the internet, Home depot usually sells the cheap 4mm bungee cords.

The best way to know if the strength of the cords are too weak or strong are to let me know the bounces per minute you are getting and your weight. If you need more bounces per minutes I will either recommend a different size mat and/or a different tension cord.
Note: if buying a bungee I make sure it doesn't keep me in the air too long. Its only at the bottom of the bounce, when there is just enough ballistic impact open the valves to move the lymph fluid to the liver. THE VALVES ARE NOT OPEN DURING FREE FALL AND WHEN THE BODY IS AIRBORN AT THE TOP OF THE BOUNCE. THIS IS THE REASON I TRY TO AVOID REBOUNDERS THAT KEEP ME IN THE AIR REALLY LONG. This is why I only promote bungees for cardio and toning only.

If the acceleration does not have enough pop at the bottom of the bounce and it instead throws you up, this is good and all when you want to allow the body to do more dynamic exercises but for lymphatic bouncing, I don't recommend them.

The tapers at the end of the springs are what gives the pop and G force to open up the valves. Depending on a persons weight, the Lymphaciser is the best for some people while the Cellerciser is the best for those that have bad backs or with certain conditions that can't handle any jarring. Rebounders with only a single tier are great just for the health bounce. When I go to the park and someone gets on a rebounder thats designed with a short coil spring just for the health bounce and they try to jump high, this is a give away sign that its not for the health bounce. Just like when someone jumps on a bungee, they start jumping really high and then get on a Cellerciser, and they instantly say the Bellicon is better. People looking for high bounce won't like the spring rebounders and those in my videos looking for the health bounce will stay away from the bungee. (see my Bellicon Vs Cellerciser page here).
NOTICE: I AM TIRED OF SPRING REBOUNDER COMPANIES KNOCKING THE BUNGEE REBOUDER SAYING IT IS NOT GOOD FOR LYMPH DRAINAGE. Maybe you can't do the health bounce and pump the lymph valves but if you study the lymphatic or have ever dry skin brushed, any up and down force to the skin move the lymph in the "lymph capillaries" but the bungee depending on how firm it is can have a hard time pumping the larger lymph vessels near the organs. This is the hardest part as you don't want a spring one that will jar you to do this.

If buying the bungee, almost everyone I talk to ends up getting the extra strong band and those who become upsessed with it, end up buying cords every few months to keep up the tension. There are some people who can afford it who buy a set of bands every month. Usually this is when a family is using it.
NOTE: Those who get the wrong tension they are not going to be able to sink down the mat while those that are too heavy it can have a hard time springing them up with enough G force unless they jump even higher out of the mat.

Note: The only times I WON'T recommend a bungee rebounder is when someone has a back, knees or ankle problem. The low jarring the bungee is not what can hurt the back or with someone who has bad knees, its the jumping too close in the center where the ankles cock in.

I highly recommend the bungee rebounders for cardio workouts or toning up. The Bellicon is the best I've found if you are using it for one person but if a family is using it the JumpSports is more suitable. You can control how airborne and how firm or soft the cords are since they are adjustable. If the main goal is fitness, the bungee is great. If for health or lymphatic drainage, then hands down the spring. 
The hexagonal bungee rebounders are the latest in bungee rebounders that are imported from Europe. These are sold for 99 collars but the shipping is $120. The shipping costs more than the actual rebounder. Just like people get cheaper rebounders and try to replace with Cellerciser springs, the last person I talked to bought one of these and replaced the bungee cords with the high end bungee cords. If you want to choose your tension and the cords that come standard with the hexagonal are too firm or too soft, I recommend having a back up pair. If one cord breaks its always good to have a back up pair on hand so you don't have to wait to have them mailed to you.
Note: Depending on the weight of the people using it, bungee cords must be changed out about twice each year. That's the main thing people complain about but if people can afford an import rebounder. If someone's 200 pounds or more and they want to keep close to the tensile strength that the new bungee cords have, then possibly 3 times a year.

Note: On my Bellicon, I try to change my cords 1/4 inch after every 2 to 3  times I use it. The metal ring attachment on the cord can rub through the bungee cord if it is rotated on the frame. Make sure you rotate the metal fastener always never touching the frame. Also note that if one bungee cords break after a few months then I have to change all the cords so I can have even tension. I can't change out the one cord that broke. It can be very costly if someone is lazy and not rotating the cords 1/4 inch every few times. Also if I am watching tv and always facing a certain direction, my feet are putting more stress on those 2 sides of the mat. I lift up and rotate the entire rebounder clokwise 90 degrees after every worout so I am not wearing out those same spots each time. Putting all the G force from the bounce on the same sets of cords each time.

Note: If you don't have the balace bar with a any bungee rebounder, I strongly recommend using the cover to go over the bungee cords. The Jumpsport bungee now comes standard with the protection pads that fit over the cords.

See most popular review between the spring vs bungee rebounder here. Bellicon VS Cellerciser Review
50 inch frame, 39 inch mat
Those buying a bungee rebounder over 28 inches: 
Note: the rebounders like the Urban and Jumpsport bungee that have smaller mats I am not concerned about inversion.

Most of the problems people over 200 pounds have are with larger mats even with extra strong bungee cords. As it takes more amplitude to gain G force it also sinks in the mat lower to the floor which can cone in more no matter how heavy a person is as long. A 200 pound person might get 5 G forces while a 100 pound person might get 1 1/2 G force bouncing at the same height. With the bungees the heavier the person is the more they must sink into the mat before gaining higher amplitude. This makes it almost impossible (without a balance bar to push back into the mat) to gain G force without leaving the mat. 

It is a big headache for most people as about 5% actually get the right size mat and tension. With spring rebounders its much easier, the springs are in the equation. If someone gets the extra strong tension cord, now if they buy the wrong size then I have to worry about the mat coning in after the cords become medium strength from extra strong after 6 months of bouncing. Bungees can lose their initial tensile strength of the rubber cord very quickly with heavy usage and heavy people and most especially if the wrong size mat is used.
Nearly every Costco store has a bungee rebounder area in their store. If you want to try one, let me know what the bounces per minute you had and what tension setting you adjusted the cord to. If you are deciding on a Hexagonal or Bellicon model this will give me a better idea of what tension to pick out and what size to match it to. Most people just think they want a really large one or they think a small one is fine but when they get it the mat size and cord strength are so mix matched that its not even funny. And then they get mad and wonder why the boucne is too soft or too hard. Please don't give rebounding a bad rap if you are the one making the mistake of getting the wrong match.
