Tennant! Definitely!
He had the most lovable episodes, and was the most well-rounded doctor, really. Eccleston was the most serious, and Matt is too cocky. Tennat is the nice middle ground.
(Although story-wise it makes perfect sense. Eccleston just got out of the TIme War, so he has to be dark and broody, Tennant is learning to cope with new life/power/whatever, and finally Smith is where the Doctor's character finally feels all-powerful and what not.)
