I liked Peter Davidson as the Doctor. He had a hard act to follow.
He really did have a tough time. I think that in many peoples' minds, Tom Baker was the "Ultimate" Doctor.
Somewhere at home, I've got a photo of Peter Davison at a HHGttG/Dr Who convention in St Louis from... Oh, it has to be from about 1985 or 1986, where at the banquet, the DotD was wheeled out to him! If I can find it, I'll scan it in and upload it.
