I don't like Edgar because his best attack, Chain saw, only does 5000 at best.

Cyan's sword techs get old fast. It sux having to wait a good 10 seconds letting the enemies beat on you just so you can hit them for 2000.

Gogo is good but you get him very late in the game. I usually don't get him as soon as I enter WoR, because the Ninja's in there can kick my ass all over the place.

For what, exactly? Nothing specific, just your general best party. I'm having a real hard time because most characters have some sort of flaw that makes them vastly inferior to the others.
(Note: The above examples are based on near end of the game.)
