I fell the All-Star Music Suites have much more "living" room and a separate kitchenette and closets, which leaves a lot more room in the gathering area. AoA has a little desk/kitchentte area and a locker for a closet in living room. The 3 kids can all sleep in their own beds at ASMu vs. 2 of them having to share in the AoA suite.
You're giving up the "newness" of AoA so you need to look at what is more important. For us, we would always chose All-Star Music because of the space in the living room and the closet space.
