X is the only one I found it near useless because for one the character its restricted to I didn't use most of the time and it's harder to abuse overdrives in X until late in the game over VIII which you just need to keep your character in the yellow and you can have one every turn.

It can be annoying to get the spells in the games that require the enemies to hit you with it like in V and X-2, but VIII, IX, and X they were fine.
