Black star is better for people who can't get grand souls easily. That way, every bandit you kill has a grand soul.
However, if you're a mage and can summon a dremora lord, you can stand at the enchanting altar and summon the dremora, trap his grand soul and use it, then rinse and repeat. If you made the Black Star, you'd have to go out to a bandit camp and trap a soul, then go back to the altar, etc.
So Black Star is better for warriors and thieves, azura's star is better for mages who can summon grand souls.
