I much prefer old, hippy-ass prog over prog-metal. I mean, I like the stuff, but I don't care much for the power-metal oriented ones. If I want to hear prog, I'll blare some Yes's Magical Underwear live album, maybe a video of Peter Gabriel prancing around in a toga. If I'm craving power metal, I'll blast that one Kamelot album with the hot chick, maybe one of the older ones like Halloween or some Tolkien-based crap. If I want both, I'll blast Symphony X (they're cool), but I can't exactly put my money behind most of the others in that field. They be not my thing.
Regarding the genre in general, I do like more subdued stuff, like PT, Russian circles, and Ancestors. Speaking of PT, their best stuff is from when they were psychedelic or alt-rock. The metal stuff's still cool in my book, but they're at their best when subdued and under the influence.
