He's good... but I'd be hard-pressed to decide on the best FF charecter ever.

Cecil was pretty good... Squall not so much, although he is my fav male lead.

Garnet is actually the most interesting IX charecter to me... If I'm reading into the game right, her past is more convoluted than Vivi's... But I'm only about 1/4 into disc 2, if even that far, so I may be wrong.
