To answer the question: I commute on all my bikes from time to time. 3 of the 4 have drops, which I prefer. The other is an old MTB with flat bars and bar ends. Even with the bar ends, I find it to be much less comfortable for my hands.
My favorite bike to commute on is the one in my avatar picture, my SSCX. For commuting I swap wheelsets from knobby and freewheel to slick and fixed.
