Which characters have the Limit Breaks you love? What characters have LB that you really hate to the point where you hate having that character in your party?

For me, Quistis's Degenerator (spelling? gah, it's late!) saved my ass many a time in the Deep Reseach area. Selphie's Rapture can be nifty as well. (I've yet to see The End as an option)

I don't like using Zell's, mainly because I'm playing the PC version of the game and I feel like a spaz trying to hit the keys and always somehow mess it up. So I generally use him to heal or cast something else like Meltdown.

Rinoa's Angel Wings can be too unpredictable.
