All similar, each different in its own peculiar way. If money were no object, I'd probably go for a Pinarello, based on fit more than anything else. And Treks fit a little smaller than Specialized or Pinarello.
That said, working for a Trek dealer, I ride a Madone. Cornering is very quick and precise. If it were a little looser up front, though, I'd like it better for bad roads.
