Except it is true. It is one story and he couldn't end what he wanted. Kefka wanted to restore the statues so the planet is devastated (succeeded) and he became stronger. Afterwards he also brought more destruction.
Kefka's goal was to obtain more power and devastate the world. It was a complete success. He even ruled over the destroyed world for a year.


Sephiroth wanted to summon a Meteor (succeeded) and wound the planet so he could get easier access to more power by the planet trying to heal itself. Both succeeded in one thing. Kefka just had destruction and then another destruction afterwards, whether it was by restoring the statues or not. It was still just destruction and nothing else. he succeeded in doing one of them and afterwards he failed again like all of them. Also his restore the statues plan is a mid-story plan like all villains have and succeed with (free the void, summon Meteor, absorb more souls for Trance, et cetera).
Sephiroth did not succeed. His goal wasn't to summon a meteor. The meteor was just his means of creating a giant wound in the planet(so the lifestream would be forced to gather). His goal was to obtain the god like power(much like Kefka). He was to absorb the lifestream and become godly powerful. The party defeated him before he could succeed though. Kefka actually obtained the god-like power he was after. Hence why Kefka succeeded and Sephiroth failed.


Though he's only my second favorite of the series next to Kuja.
This. Kuja is definitely the best. I just wish he wasn't wearing a thong...
