Uh, actually you're both wrong.
Gear ratio is not affected. Nor is gear inches. Only your gain ratio is.
Some people have claimed that the bearings on the BB have a short break-in period.
I used a torque wrench with one pair, but they're supposed to be set at 50lbs (double-check this, it's from memory). That was high enough to meet that I ended up wrenching them with a pretty great deal of force. Didn't bother a second time. I was more worried about the torque being set much lower to avoid crushing the bearings.
Edit: Also, as far as the BB types, since omniums use external bearings, they're extremely stiff because they bolt directly to the other arm. Square tapers are weak and whack (IMO)... people bone Sugino 75's because they say NJS on them. If you put a 225 lb guy on square taper cranks and have him stand on them horizontally, you can see the arms flex down.
