I think I'm a little strange since Fear of the Dark might be my second favorite Maiden album (generally disliked by many?)
But it holds a special place for me since it was the first album I heard of theirs in the 90s.
I'm not a huge fan of Powerslave, I usually prefer Maiden's catchier tunes opposed to their progressive stuff. Also strange since I'm a prog nut. Piece of Mind, Killers, Self Titled and Somewhere in Time are all fantastic as well.
