What's more important is which one you like. Nothing wrong with any of them, pick one and roll.

Soon enough, you'll be infected with N + 1 and it won't matter.

My first fixed gear bike was the Bianchi San Jose. I felt the Pista was too aggressive(plus the one I rode was a bit small). San Jose is more versatile and came with brakes. Brakes are good things to have.

What type of riding do you do or hope to do?
