for me, its simply what mood I'm in. Moe gives me things that SCI doesn't and vice versa. When I'm feeling a little agressive, Moe hits the spot. But when feeling mellow and kind, SCI hits it. I'll be let me see....Moth or Birdland? (for example) and sometimes its a hard decision. Overall I enjoy SCI, and listen to them, more often. I think SCI's sound is a little more complex, in a good way. But hey, It's all good, I dig a lot of Moe material. When no decision can be made, I default to the Dead, always.
