I love the album, and I love the mix. A 10 for me on this one is not a question.
THe mix is amazing to me because it is "aggressive," but in a very apporopriate way. Even discs like "A Night At the Opera" (which I would rate at a 10, also) tend to use gimmicks at certain times in an inapporopriate way. On this disc, if there's something "circling overhead" ("gimmick" at its best), it's because it should be, not because it can.
