For me, the best traditional animator has to have been Chuck Jones. I grew up watching the likes of Tom and Jerry and it always had me fascinated...still does

I guess the same could be said for Fred Quimby and Tex Avery.
Art Babbit did some awesome stuff for Disney too. There was always something magical about classical 2d animation. You dont quite get that now sadly...
Other favourites are Matt Groening, Nick Park and Tim Burton (Nightmare Before Christmas is fantastic!!)
And of course there is Ray Harryhausen and his inspirational work
As for 3D, I guess Pixar gets all the plaudits. The benchmark!! Blue Sky also....Though I really like Mark Behm's style

As for best character, well Homer Simpson is so damn funny but then again Ive always liked Wile E. Coyote - some sort of empathy I guess lol.
