Yep, those 3 and McGuinness are the best at Marvel right now.
Carlos Gomez, Bradshaw and Medina are a tier below them but still very good and I'd take any of them full time on FF but I think FF hasn't had a top tier artist in years.
Jim Lee, Larrocca, Pacheco and Ringo were the last I can remember.
I actually really love Kim Jacinto’s art. He’s probably in my second tier, along with Javier Garron, Pere Perez, and Carmen Carnero.
