I have a better one this time:

Orlandu-
He is extremely overpowered with Swd Skills like Lightining Stab or Holy explosion. He can kill anyone with no problems

Magus-
CT is okay right? Well, his spells can do incredible amounts of damage to enemies and he can even add magic defense to your party. He is also a decent attacker.

Celes-
Celes is a great magic attacker, and healer for the party. She can absorb any magic that will attack the party. She can make use of most equipment and she can attack very well.

Cecil
Hmmmm.... He's just a juggernaut when the Ragnarok is equipped.
