I do think the Born Again era, continued along from the Dio era, which is my favourite of all the eras, it sort of continued that progression I believe, especially with cuts off Mob Rules like The Sign of the Southern Cross, Voodoo, and Falling Off The Edge of the World, thats just my opinion. But I do agree that it was a fantastic era the BA one, that any Sabbath fan must check out, just as underrated as some would say as the Tony Martin one.
Piece of Mind used to be near my top 5 Maiden albums, but fell below my favourite album which is easily PowerSlave, followed by Seventh Son of a Seventh Son, Caught Somewhere in Time and then either A Matter of Life and Death then Piece of Mind. (However Where Eagles Dare, Revelations, Flight of Icarus, Die With Your Boots On and The Trooper, all Maiden classics from that album that are beyond awesomeness.
