Chis,
The current is related to the wire size, and the voltage to the number of wire turns. The power is related to the weight, so weigh them, and the heaviest likely has the most current out. Try to find out all the specs, manufacturer, etc. Google any part numbers. Are they marked with the speed at voltage? The load should not draw more current than the wire can stand. If driven continuously, measure the temperature to check maximum current tolerable. If you can't hold your hand on it, it won't last long.

Both turn at 500 rpm. Which motor would output more amps?
