All manufacturers and all servo types have some form of a failure rate. We, as consumers, will never be told what the rate is. No big deal. If you receive a bad servo from any of the manufacturers, generally the standard process is to return the servo to the manufacturer. With JR products they would be returned to Horizon Hobby and I can rest assured that you will be provided excellent service. Give them a call and you will discover that first hand.
As far as who the best is concerned, I've had bad luck with brand X, a friend has has bad luck with brand Y. I've had nothing but great experiences with brand Y, he's had great experiences with brand X, so who do you choose?

I'm currently flying some rather large, unusual, and costly aircraft at the moment, and the cheap ones aren't even considered for use. The craft manufacturer has the choice of anything currently available, and all of your money they want to spend. Go figure.

Perhaps they get used in most of the 40% planes and as such are purchased 14 at a time, thus depleting the stock that much more quickly?
The extreme flight Yaks are in.....the DA 50 supply is drying up and so apparently are the servo supplies...
Could be a lot of reasons for them being sold out.
I personally like both brands and have had no issues with either.

Hey guys, maybe its not the JR..... I got in my new PCM reciever from tower today and hooked it up to give it a shot. The servos dont make near as much centering noise and I walked out 400ft plus with the antenna all the way down, and NO jumps, interferance, or anything.... I think the digitals were in some way screwing with the FM signal. Do you guys think its ok? I mean its completely fine on PCM, the JR doesnt sound like its continually centering now, it sounds like it hits center and holds it. I think its all good. I cant wait to fly her tomarrow.

First and foremost, any digital servo worthy of the title should always be making some noise holding center if there is any weight on it. If, without anything connected to them, your flight surfaces were perfectly balanced where they would remain in absolute neutral, then, and only then, would a digital remain quiet. The signal sample rate for a digital is much, much higher than an analog, and it should do everything in it's power to perform the task it has been assigned to do.
Second, installing a PCM rx in the attempt to mask or reject an internal issue that you are already aware of is begging for disastrous results. PCM should be used for the rejection of minor stray and outside rf issues, not pre-existing problems. When a PCM rx goes into failsafe mode, it doesn't care where the interference comes from. If the interference comes from inside the plane, it can, and has, failsafe all the way to the ground.
Bottom line, if you know you still have a problem, find and fix that problem before you fly the plane with any receiver type! If you are getting a good range check, based on the radio manufactures suggested range test proceedures, then you should be ok. The difference between the range test differences with a PPM receiver should not be more than 10%, engine off and engine running. Leave the PCM rx out of the system until you can meet those requirements.
