Well yeah, this is a bad comparison. If you look at the indivual tracks purely, Orion wins. I wouldn't call Orion 'simplistic', especially if compared to Epilogue, the backing track of Epilogue is like 6 chords or something, so that's not an argument. Mikael's song and solowriting is far superior to Metallica's, but I happen to like the Orion solowork, although it isn't as emotional as Epilogue's. But as said, it's just apples and oranges, Epilogue is just that, an epilogue to an album, whilst Orion is a stand-alone track. If you take the poll as it is, Orion's gotta win. If the question was 'MAYH vs. MOP', MAYH would ofcourse win by miles.
