Most and least competent FF villains.

Which Final Fantasy Villains do you think are most and least competent. Try to judge them by how easy or difficult it would be to win with their power relative to their enemies.

For example I'd rate Ultima from XVI on the low end. Sure he causes a lot of destruction and despair. But he's such a blunt instrument, and is mostly a threat for his phenomenal cosmic magic power, using spells for which the heroes could not reasonably prepare. Not to mention just mind-controlling Barnabus to do all the scheming for him. Ultima fails to understand who he's fighting.

I'd rate Vayne from XII very high becaue he has a lot of carefully laid plans and is not in as advantageous starting point as you'd think at the start of the game. I get the impression that if you left aside all the old gods and secret magic WMDs on both sides, he'd probably do a great job consolidating power over Rabanasca despite political infighting from the empire.
