I really, really liked Eccleston in the role. It took me a long while to accept Tennant and for a long time I kept saying 'I preferred the last guy.' But eventually, Tennant replaced Eccleston in my affections and he was my then-favourite.
I loved Matt Smith basically from his first appearance in the role and since then he'd been my fave Doctor, not only of this three, but ever. I can only hope but TPTB keep this winning streak up and that nuDoctor is yet again even better than his predecessor.
