Heh, the only one I hate in those listed is Rinoa.
Tellah - I can tolerate even with the 90 MP limit because he's the only solid mage you have at some point in FFIV. And he's more useful that Edward. (Don't get me wrong, I don't hate Edward and his spoony bard-ness, I just think he's useless in combat).
Umaro - Must be a trend, I usually pair him with Cyan too... >_>
Cait Sith - He had his moments where he iritated me, but I don't hate him.
Quina - Come on, now, Quina was just plain awesome!
Wakka and Rikku - No opinion on them, as I have never played the game.
