With my fitter it was #2 , #3 . I put comfort last as I have a hybrid, MTB which I can tool around in - albeit slowly. That said after a few hours on the carbon bike I feel it a little bit in my lower back. But not much which is pretty cool given that I am not all that flexible. Mixing it up between bikes is pretty good overall, though I must say I like being able to blow away other roadies if I am with it that day, whereas I can't do that at all with the hybrid, MTB, and barely with the belt driven bike I recently got.
