Mindcrime is NOT my favorite album, so the "besides" part of the poll is irrelevant.
This is a tough call for me. For years, I ranked Promised Land as my #1. I love the loose concept of it, the dark, angsty vibe, and the huge atmosphere. I used to get lost in that album like no other. And some of the songs are just stellar.
Empire was what REALLY hooked me on the band. Yes, it is more commercial and polished. But it is SO well done. It is just about the perfect album. Almost every song, even the ones I have grown tired of almost 30 years later, is incredibly strong.
I went with Empire.
