^Five's one of my top faves. Actually I think it's why I like Eleven so much is some aspects of him remind me of Five. Both bring more of a "humany-wumany" factor to the Doctor.
I like Four a lot, and I saw quite a bit of that in Eleven too, and Ten.
As an aside, to me, every incarnation is unique, but also reminiscent of a past one or two since his core personality traits shift in dominance, but never really disappear. The Doctor is still
The Doctor no matter what face he has. Essentially the same person.
Evidently way later in life he gets to where he can pick out how he wants to look al la Romana trying out different looks before settling on her Princess Astra form. Regeneration becomes less of a lottery if you figure out how to do it...
