The first pair is the hardest I've come across in this game so far. Two absolutely brilliant albums, and in fact, the best albums for each given band. Breaks my heart, I'm voting for AMOLAD, because I have a more personal relationship to that one, but this is not fair. Not when all other rounds/pairs are completely on a different level.
I seriously dislike Ryche, but Mindcrime is a (mostly) great album. The storyline is overwhelmingly banal (so it goes with most concept albums, though), but stuff like Mission, Sister Mary Suite, The Needle Lies or I Don't Believe in Love, when taken together, give much more of an epic feel than the Priest album, good as it (again, mostly) is.
Ride the Lightning is probably the second best Tullica album, the title track alone beats pretty much eveything on the Maiden one. Count in Bell, Creeping Death, even Fire or Ktulu as well and you get a curb-stomp battle here. I actually like TBOS (and I was a huge fan when it came out), but I've grown colder towards it. TRATB, TGU, the title track, Shadows and possibly even Eternity and River are as great as ever, but there's really a lot of fluff (Death or Glory, Speed of Light, Sorrows, Clown - oh, the banal themes of the latter) and Empire is... bloated excercise in self-indulgence. The primitive piano in the beginning, the melodrama both musically and lyrically, the grinding-to-a-halt SOS section (no, it's not a good idea), the ridiculous length... it just symbolizes and incarnates everything I hate about the unbridled Dickinson adoration. Yeah, huge words, huge concepts, but still he is just a businessman after all. Too small-town for me. Even when it tells the story about a tragedy of an airship. The poetry is forced. Such a waste of space.
I'm gonna go and give Among the Living the pity vote, because it's gonna get massacred here. But I genuinely love the album and it's probably more consistent for me overall than the Maiden one (at least it has nothing as obnoxious as Heaven Can Wait). Sad to see this one go, what are you going to do? Thrax all the way!
