There seem to be a lot of half-truths floating around here....
While the CIM has up to 346.9 oz-in of torque (2.450 N m), the Bosch has 0.870 N m of torque, and the Johnson F-P has 0.6375 N m of torque, all of these numbers are measured at different rotational speeds. To get a comparable measure of which motor is strongest, you should compare the (mechanical) power of the motors, which equals speed × torque.
At 12 V, the CIM has up to 343 W (0.46 HP) of power, the Bosch has up to 448 W (0.60 HP) of power, and the Johnson F-P has up to 262 W (0.35 HP) of power. Therefore, the Bosch drills are the most powerful, followed by the CIMs, then the F-Ps. (I say "up to", because the maximum power of an electric motor occurs at a single point, in the middle of the power vs. torque curve. Everywhere else, it makes less power.)
Note that these numbers assume that the drill gearbox is
not being used.
While the only way to really examine this in detail is to look at the
graphs, this should be enough to base your assumptions on.
And if you're wondering, 188 used all of the above motors to drive its robot (all at once, of course).
