Fourth and ninth were really very good. To be honest the only two I wasn't really fond of were Six, who was a bit too violent for the character, and One, because... mostly because of the Five Doctors actually. That sort of bashed my view of Hartnell...
The one who played the First Doctor in "The Five Doctors" wasn't actually Hartnell. Hartnell had already died at that time (he died in 1975; the story was in 1983). The actor in that one is named Richard Hurndall, though the pre-titles bit ("One day, I shall come back. Yes, I shall come back.") was Hartnell. I think Hurndall played the character somewhat differently, but I haven't seen much of Hartnell's Doctor.
Sorry to be so strict about it, but I thought I'd just say it...
