Pick your best characteristics?

I'm looking forward to Peter Capaldi being the Doctor so much, mainly because he's such an awesome actor, and I don't use that word lightly I can tell you. I feel he'll bring so much more depth.

That said, what characteristics where your favourite from McGann to Smith.

McGann. Vunrability
Eccleston. Hidden bubbling anger
Tennant. How his eyes told a story
Smith. His compassion
