I agree with Bare on this one. Testing to confirm manufacturers specs is needed for one thing. Aside from that, what constitutes the "best" servo will depend on what the application is. Do you want high torgue, fast speed, small size and weight, low cost, or what?
It would be interesting to sort the existing list by these factors to see what servos float to the top in each sort. From what I can see, the Futaba S3114 would be near the top of the list in most of these categories. Gee... that just happens to be the one I use!
It's hard to rate reliability and quality... FWIW, I've had some really bad experience with GWS Naro Std. and Hitec HS-55 servos, which are very common and widely used.
