Kefka vs. Kuja

I have not seen Kuja, but if Kuja is simple brute/mystical strenght marked with expert/godly skills... He would not be able to do much against Kefka. Through his pathetic appearances and deceiving personality lies a twisted mind of a functional mad man, capable of destroying a kingdom and avoiding notice, ensnaring people into his traps, picking away his oppositions one by one, maintain a hidden profile underneath watchful eyes, manipulate people from behind the shadows, act like a bastard and a crybaby, pilot heavy machinery, recreate the world to his own wishes through the absorption of many different magic including the source of all magic itself. (Meaning, Kuja could not do much if he relies on magic, due to the fact that he'd be fighting the source of his own powers, technically)

The list goes on about how vicious Kefka is, it may not be obvious, but if you look behind the curtains, this is either an extremely long twist of lucky opportunities for kefka to follow in his wretched trail of chaotic destruction, or a beautifully planned out path to his own utopia through mindless chaos which will bring to him his final prize and glory, no matter what the opposition may be and no matter what may happen, for with quick wits, he could remove himself from any dangers and situations...

Due to the fact that I have little to no information on Kefka's opponent, I cannot say anything about this Kuja, therefore, to me, by Default, Kefka's the winner.

Well, not giving away spoilers:

Kuja is simply a powerful mage. His build is light and he never employs any physical attack. Simply magic. He too has a devious mind, and manipulates a continental war and chaos, through the greed of another. He has a mind for deceit and mamipulation, same as Kefka.

Kuja, at the peak of his power, was able to annihilate a planet. He also took out your entire party in one attack. He is a cocky person, but he is a no bullshit fighter. He'll kill you, laugh while he's doing it, and then just walk away, after making a eloquent quote of some kind.

I'm not sure who'd win, but I know that it be a spectacular sight to see.
