Something nobody has mentioned is that /SCH gives access to weather spells and Klimaform as well. That means more accuracy for your spells and if you have the right gear (Obi + Twilight Cape) you get a 15% multiplicative (with your bonus from your staves) bonus to your nukes (all except thunder, dark and light based spells). That said, for Black Mage main, the choice isn't as cut and dry as White Mage main - sub job choices will be more situational by far.
/RDM for solo for haste, gravity and phalanx. /SCH in a party is good if someone will cast haste on you. Marches DO stack with haste spell and gear and fast cast/arts for timer reduction. I use haste gear on BLM for drain, aspir and stun. On WHM just for flash and haste cycles.

Only dual wield and martial arts are multiplicative and that's obviously for meleeing, not recasts.
