I was pretty devastated when Ten regenerated - those awful last words just broke my heart. He was also my first Doctor (I'd watched the show a bit as a kid, but only got into it in season 2 of the reboot) so I felt rather attached to him. But I am loving Eleven. I made a list of my 10 least favourite Who episodes for a meme a few months ago, and since there was only one Eleven episode on the list, I take that to mean he's doing pretty well. :p
The episode in question was 'The Doctor, The Widow and the Wardrobe', btw.
I guess it helps that I really love Moffat's episodes and story arcs in general. But I don't tend to compare him and RTD much; I love both of their directions with a few exceptions.
Rose Tyler living happily ever after with Meta Crisis Doctor, that ending was just such a pretty little parcel. >>
