Xurts, you may not like Zidane's personality (i'm sometimes iffy about it myself) but you cannot discredit him from being an exceptionally good character to play as, just like Steiner's an arrogant moron most of the game but he's very strong. Zidane's physical attacks are strong, his Trance attacks are extremely useful against boss fights, and from what i've seen and heard about Thievery, its good too, but i rarely bother with stealing unless its bosses.
