Eccleston was my first and in a lot of ways I'm not sure anyone has ever topped him in my estimation. That said, I'm pretty sure that, forced to choose between Tom Baker, Eccleston, Tennant, and Smith, I couldn't do it. Peter Davison would be pretty high up on the list too, and Patrick Troughton is no slouch either.

I kind of hope for the new Doctor that they cast someone who's either not white or not male. Or both. Either that or a ginger.
