TM motors are the most reliable in my experience but are no where near the top for torque or speed, they are the best for energy efficiency as TriChrome says.

G&P motors are really nice for the price, much better performance than TM but they have been known to fail much sooner than TM motors.

SystemA Magnum is the best motor there is that I have tried (and I have tried practically all brands.) It has insane torque and speed which delivers much nicer trigger response than anything else. It actually has a higher speed than the SystemA Turbo. It does cost US$79 though...as for the new Magnum I have no idea.

In terms of speed vs. torque always go for torque. A good high torque motor will actually have faster trigger response and a higher maximum speed under load than a high speed motor. With the exact same internals a SystemA Magnum gives 2rps higher ROF than a SystemA turbo in my ICS CQBR. Fires 26rps with the Magnum, 24rps with the Turbo, and 21rps with a TM EG1000. The Magnum is power hungry though, you will drain batteries faster than any other motor and its really good to upgrade to 16 or 14awg wiring for the extra amperage.

Lots of people complain about the crappy pinion gears on SystemA motors and they do strip a lot faster than any other brand even though its supposed to be chromoly hardened steel but once its properly adjusted they last forever. While playing around with different gear sets you can strip a pinion gear on a SystemA fairly easily, but once set I have run them for tens of thousands of rounds with very little wear showing up on them. They do have by far the easiest to replace pinion gears though, just need an allen and some loctite, no special pinion gear removal contraption required. TM definitely win for the most durable pinion gears.

Guarder are nice but I find G&P outperform them. CA are junk with a high failure rate, nice if they run but unreliable in my experience. JG and other China brands are crap, worse than junk; they run fine if they work but have a ridiculously high failure rate even out of the box and seem to have random torque from motor to motor, zero consistency.

Best motor: SystemA Magnum
Best bang for buck: G&P M140 torque type
Best for reliability and run time: TM EG1000

*Edit*
The new SystemA Magnum is rated for springs up to M170...but what about the Prometheus M210 that is available?
