With regard to functionality and tuning stability? I have stock stratocaster tremolos, Bigsbys, etc. As far as being a pain in the butt to string up, the Bigsby beats the Floyd Rose in my opinion. In terms of functionality, it seems I can do anything with a Floyd that I can with the other two types, and far more in fact. I understand that there are probably people who hate those things based on the types of guitars they're attached to ("shredder"-type guitars), but take that out of the equation and I think the Floyd Rose is the best overall trem system in existence. NOTE: I've had Kahlers also and liked them too, but not as much.
