Position 1 on my TT bike (which isn't just about stem height but a entirely different set of bars and saddle position)
Position 2 on my road bike
Position 2.5 on my CX bike
Positions 4 and 5 make my ass and back hurt after a few miles. It's counterintuitive, but I find being low, stretched out, and most importantly weight balanced fore and aft to be most comfortable for long miles.
