Leveling Materia Melds

[MistakeNot]

So I'm leveling a Black Mage and a Paladin and I'm wondering what Materia I should be using.

Reading older posts suggest that Critical hit isn't good until you can stack enough of it but other posts say that Crit is the best for BLM.

Really doesn't matter while you are still leveling. Even at level cap the exact materia you use makes only a small difference.

Crit and Det works fine for all classes, jobs, and roles. Not always optimal, but always useful.
