Lower kv motors generate more torque than high kv ones, all other things being equal, or so I've been lead to believe...

Spinning it faster and gearing down would certainly generate more torque for certain, but if we're going to extremes, a very high kv motor would suck ALOT of current, geared down or not I would expect. Lower gearing would reduce the load on the motor and therefore reduce the current draw etc, but at any given throttle amount it would still draw more current than the lower kv motor pullig taller gearing I expect, so.. I dunno, I think its personal preference really so long as the kvs, voltages and gearing are fairly sane.

Too many variables and unknowns for my liking, one could spend a long time doing bench testing with dynos and simulated loads to find the real answer...
