Of course you want a servo that can do the job but the main thing is relliabllty.

The most important thing is matching the servo to the job in hand.
No point in using a high spec servo in a cheap trainer nor a cheap servo in a high spec model.

To me, reliability is how well all the components work together during the life of the servo. If any component fails, the entire servo fails. If I were to pick stall torque as most important from your list yet the servo arm breaks during a snap roll, reliability was still the most important factor.

Assuming the servo is 'reliable' in normal use, then my guess is you would get different answers from each pilot based on the demands of their particular aircraft. Pattern guys will be more interested in things like centering, gear lash due to the demands we have for precision, while guys that are into 3D type maneuvers might be more interested in torque/speed, stronger gears, etc.

From your list, I would probably pick 1, 3, 8 as the most important to me, assuming the servo is appropriate for the application I am using it in (pattern).

1) Reliability, first and foremost.
2) I also think about how the servo might be used in the future. I would rather spend a little extra and get 'more than enough' so I can use the servo somewhere else if need be. I hate having a new plane to put together and a bunch of servos laying around that aren't strong enough to use.
3) Reliability.
4) Accuracy.

I would first consider whether the manufacturer employs shills to spam public forums to promote their product under false pretenses.

To me the most important thing is the price.
They all have IC's,motors and gears made in the same place.
And I can check to see how well is assembled.
