More accurate jobs:

Tidus- Paladin
Auron- Samurai
Yuna- White Mage/ Summoner
Lulu- Black Mage
Kimahri- Blue Mage/ Lancer
Wakka- Blitzball Player
Rikku- Thief

But yeah, I like Auron's. All those "break" abilities really helped me out. Kimahri's is cool too. (Blue Mage and Dragoon? Two of the coolest classes in FFs combined? ) And of course, Black Mage, Lulu.
