I vote for The Wicker Man, with Different World in second place. As many know on here I hate Wildest Dreams, in my opinion easily the most mediocre thing Maiden ever produced. I suppose The Wicker Man is more of a sentimental vote since I've heard it more than Different World and it is the opener to Brave New World. But that chorus just gets me, and even the "sing along" part that some complain about. Makes for a great live song in a large venue.
