I cant answer. I am 50/50 :zombie:
It's hard to say, given just those two options.
I like a lot of power metal in the American style (thrashy, darker, not as bombastic), but I like almost no Europower, which seems to be the far bigger draw for Glenn.
I like a lot of what I consider prog metal, but those bands tend to be more musically involved than the prog bands Glenn books. I don't consider bands like Vandenplas or Threshold to be proggy at all.
But I realize I don't fit the mold here, so I'll shut up now.
Personally, I am a Power person. Some Prog is OK, but I just like to get dirty, headbang and throw some horns!!
I'm surprised Prog isn't dominating this poll as much as I thought it would, given the nature of most of the opinions on the forum. I think it goes without saying I voted for power.
I like the interesting differences in prog. I do enjoy the rock on of power too. I'd say I'm probably 70/30 for prog
