Have you looked at the motor information located at http://www.usfirst.org/sites/default...torInfo4.2.pdf yet? It doesn't include the FPs' stock gearbox, but if you can find the ratio for that, it's not too hard to calculate it. It will give you power (the real rating you want on a motor--if you don't like torque or speed, you gear it), stall torque (if it's moving and you stop it, what torque you are exerting) and free speed (no gearboxes/other loads), as well as current so your electrical crew can plan accordingly.

The FPs have more power, but spin very fast. If you can gear them down enough, they'll have at least as much torque as the window motors. But, the window motors can't be backdriven easily due to using a worm gear. They're also pretty slow--if you're winching, a window motor's free speed is about 1.5 revolutions/second, which you can convert to how much line will go onto/off of your winch per second.

Personally, I'd go with the FP--two of them with stock gearboxes and an appropriate cable-lift system can lift a robot very quickly (or, with appropriate gearing, lift a smaller high school student). But, you may need the FP speed elsewhere on the robot...

Just a few of the things to consider besides pure torque in determining which will work better...
