Kefka Sucks. Kuja Is Better

[The Crystal]

I wouldn't necessarily call Kuja smarter than Kefka. Though he was quite a bit off his rocker nothing he did indicated a lack of intelligence.

IMO Kuja went through the entire game trying to find a way to outsmart Garland, with multiple failed attempts. Kuja seemed to be on a much more winning trend in his escapades.

Just because Kuja is smarter than Kefka, doesn't mean Kefka is an idiot. I never said that.
But along FFIX, Kuja manipulated lots of people. That makes him smarter than Kefka in my book.
