I can't really choose just one, I like the 4th, 5th and 7th the most I think.
I like the Key to Time arc, they even show someone other then the Doctor regenerating!
I have been a lover of all things Who since I was quite young. I first started watching back when they had the show on PBS here. My first Dr was the 4th, but I also love the 5th and 7th.
