Eh, SCM's are cool, but I like the flavor of "Focused Abyssal Wizard/Malconvoker" (Ban Evocation and Necromancy, you'll need Enchantment to get through the lower levels.) It forces you to be creative, too. But I never make my characters as optimzied as they could be.
SCM has more power, but Malconvoker is more complex to play, which is more fun for some people.
