Iron Maiden are just Iron Maiden. If anything, their music has edged closer towards progressive metal since around "Brave new world" time, but there's no way you could call them power metal.
(This is why people laugh at Metalheads, with our multiple subgenres. I mean, we've had a page of discussion here on why Judas Priest are not power metal, and really, does it matter that much? Still, got some discussion going, so that can't be bad...)
