It's all Kefka. He was actually sucessfull in ruling the world for over a year with no one to stop him. He also split up all the protagonist, killed off entire cities, and reformed the face of the world, literaly. Sephiroth, no offence, was just a manipulated momma's boy. You also forgot looks don't make a villain. Besides, he was a total dumb@ss. Let me explain: He could summon a super nova in like 3 minutes, and yet, he settles on a stupid rock that takes a friggin' week to hit, and the end result is a dent. What's wrong with you people?
