I'm seeing a lot of mathematicians talking without any math. :-) So far, Paul's comments square with my understanding and experience.
Excepting some of the dumbed down, no choices, 90s low profile Shimanos, I've generally don't find cantis to lack stopping power, and even the worst are fine for the rear where low profile is needed. If the pads are aligned sensibly, the straddle cable makes a roughly 90 deg bend over the saddle, and the straddle cable pulls at right angles to the line through the pivot and straddle attachment point on the arms, they all seem to work. It seems like some of the very long armed low profile brakes are intended to be set up not optimized as I just described to reduce the effective lever arm. In essence part of the cable tension pulls the arms up rather than together which reduces power and increases a sense of modulation. If braking is poor and the cable/arm geometry is sensible, check the rims and pads. Squealing is the main issue with cantis for me.
