Disney has quite a few (heck, there's literally a board game about playing the bad guys and helping them win). Granted, they have a lot of villains we love to hate (for example, Jafar is a great villain we love to watch, even if we're still engaged with the heroes and want them to win), but there are some where they're just more interesting:
The only character I like more than Chenabog in Fantasia is Sorcerer Mickey.
Barbossa and Davy Jones stole the show in the Pirates of the Caribbean movies (although Jack did more thank hold his own in most of the movies; heck, part of what makes the first movie so great is the contest of wills between him and Barbossa).
Hades from Hercules: Very entertaining character with a goal it was fun to watch vs. a very boring, generic hero (actually, Hercules suffers from having a wonderful supporting cast that overshadows the protagonist).
Prince John from Robin Hood: I think Robin Hood and Little John work well for their role, but Prince John is one of the funniest Disney villains and the movie is the most liveliest when he's center stage.
Captain Hook and Mr. Smee from Peter Pan: Peter himself is pretty unlikeable and the kids are pretty bland (Kathryn Beaumont's wonderful voice performance as Wendy notwithstanding). I only watch the movie for Hook and Smee. (I did like Jane in the sequel a lot more, for what it's worth).
The scenes with Edgar, Napoleon, and Lafayette were my favorites in The Aristocats, so maybe that qualifies?
