So far I'm liking AoW more than SC. I LIKE SC, but it's a little too ... "Out There" for my tastes.
The caldera, the tropical clime, the huge variety of bad-guys working at cross-purposes, the wacky planescape background.
AoW is pretty rooted in some Old Skool type action and the bad-guys were interesting, but not in a "dude, totally grabbed a new weird monster out of MM(X)" sort of way. It's classic, and solid.
