I gave up after Peter Capaldi's incarnation, but I think I did see one episode with Jody Whittaker as the Doctor. (I thought it a neat move to get around the rule that the Doctor can only regenerate up to a maximum of 12 times (presumably as a male).)
Everyone has their favourite Doctor: usually the one who was current when they first started watching. I'm sufficiently ancient to have watched the first broadcast episode, so William Hartnell is my favourite Doctor. My least favourite was John Pertwee, playing the earth-bound Doctor, who seemed to spend all his time battling monsters in muddy disused quarries.
I saw few of the Tom Baker and Peter Davidson incarnation episodes, and virtually none of the Colin Baker of Sylvester McCoy incarnations.
