Both are potentially good bands, but...
Rosetta's wake/Lift has too much vocals. When you're ready to sit back and enjoy some nice americanized Cult of Luna post metal, you just keep getting hammered by those extremely brutal vocals chords. I mean the guys voice is absolutely intense, but come on, too much of a god thing is in fact, a bad thing. The Gallilean States would also be good, but it's too hard to try and get both parts of the album playing at the exact... same... time.
Dirge is a great band, with especially great lyrics for apost metal band, but I dont know wh they have to throw in ten minuete drone sessions in some of their epic pieces, it's just so frustrating, especially with how good they're structured pieces are!
Both are not bad though...
