Virtual XI for me, only just though, as Fear of the Dark is pretty close.
When Two Worlds Collide, The Angel and The Gambler, Lightning Strikes Twice and Don't Look To The Eyes of a Stranger are pretty awful - bad lyrics and some cringe worthy musical passages.
Weekend Warrior, The Apparition and Judas Be My Guide are pretty weak too.
Dance of Death is good, but I don't like the production. Apparently Kevin Shirley is on board again for the next album, so I hope he goes back to the sound of Brave New World!
