These offer two different riding experiences. What do you want to do? Have you test ridden both? If you intend on spending a lot of time riding, have you determined which style is most comfortable for you? Do you intend to carry items on a rack, in bags, as you use your bike for errands or commuting? Or is it simply a "go fast" recreational thing?

As Yogi Berra said, "when you come to a fork in the road, take it."
