You can't go wrong with the limbdriver. It really is an awesome rest. It is NOT without flaws though. I found mine to be noisier than my Muzzy rest. It is also not the easiest rest to adjust for rest height. You must first loosen the cord, then loosen set screws on the rest and re-adjust, then hold everything in place while re-tightening, and then re-tighten the timing cord. Easier to move the d-loop in my opinion. It is also not micro-adjustable, and I like to have that in a rest. And as far as containment, it is far from the best. Not the rest you want for stalking all day. But it is simple to set up and the concept is superb. Accuracy is also excellent with this rest.
I just simply like the complete silence (NO dropaway is quieter and this has been proven in side by side tests), durability, and total adjustability of the Muzzy X-cellerator. Arrow containment is far superior to that of the limbdriver. Rest height is as micro adjustable as it gets, launcher arm drop travel is completely adjustable with just the twist of the turnbuckle, Complete and total fletching clearance (even when shooting the largest FOBS), no springs of any kind inside or out, totally 100% weatherproof, and because there are no springs, it will not pull on your cable at all so your cam timing will be perfect.
Those that tried the original Muzzy Zero Effect rests and did not like them owe it to themselves to give the X-cellerator a try. Every problem you may have encountered was solved when they designed this rest.
Not trying to do a commercial here. Just giving you my personal opinion. I have tried and studied the Ripcord, Drop Zone, Limb Driver, Trophy Taker, and X-cellerator rests. They are all great, but the new Muzzy is the only one that can say ALL the things I stated in the paragraph above. Good luck with whatever you decide. You really can't go wrong with any of them.
