Kuja had style, flair and power. The man rides a silver dragon for crying out loud.
I personally think Kuja's stronger than Sephiroth. Flare/Flare star + Flare Star counters + Curaga = ownage.

Oh yeah, and the thong's cool.

re: :rolleyes2 Sephiroth carry jenova with him. Sephiroth is supposed to be stronger than kuja, super nova, heartless angel sure kick ass. Kuja only have flare star that lamely reduces about 1000 HP. His curaga can be easily stopped by casting reflect on him and the party (I don't cast reflect, but my vivi's flare always does 9999 damage). About the counter, my eiko is already set with curaga or full-life (to beat safer or bizzaro sephiroth, you need two KotR, while only one KotR can beat kuja). His flare, I think it as more annoying than hurt.
