Newbie needs decision help (Spoilers)

[strawberryman]

I just got the first four job classes and I can't decide which would be best to start with. Should I go:

Bartz: Knight
Galuf: Monk
Faris: Thief
Reina: White Mage

or

Bartz: Knight
Galuf: Monk
Faris: Black Mage
Reina: White Mage

Faris looks good as a black mage.
