I think all three are cool. None strikes me as significantly "better" than the other, it's more about what features you like.
Personally, I love the look of the old Volpe frame in puke green with dayglo decals.
Also, I know road triples aren't very hip, but I think that's a feature that really adds to the versatility of a bike with minimal weight penalty. You may rarely use the granny ring, but when you do, you'll be glad you have it.
