I have the Fuji and like it. It's got track geo, so it's pretty twitchy. But that also means it's nimble and speedy. I don't know about what kind of ride you get on the Masi or what kind of riding you want to be doing so it's a little hard to answer your question.
jimmytango, I'm not sure that a 6'4" dude riding a 43cm bike with 650c wheels around a parking lot really counts as riding it. LOL.
