I agree with Lloyd. Con: Extra complexity, more for the kids to learn, more possibility of things to go wrong. Pros: Extra torque or extra speed if needed. My take: I would only suggest gears to the students for an arm motor if needed.

Only use gears, if you need = gears. If you need to gear up or down then it's worth it. If you don't = need to gear up or down, they become one more moving part that can go = wrong and/or cause inconsistency. I've always liked the idea of = simplicity, the less things that can go wrong, the better.
