Metridium Fields is an amazing album, easily on par with Panopticon and Oceanic, but The Icthyologist, despite it being good, isn't of the calibre of those two. I don't even think it's on the same level as Wavering Radiant or In the Absence of Truth, so I give the edge to Isis. Could never get into Neurosis, don't know why. I really shoudl try again, I haven't listened to them since I was in high school I think. Mouth of the Architect is pretty sweet too, but I like Isis more. Don't know Rosetta very well, not sure why I never pursued them more. Just never got around to it I guess.
Oh and look, Mr. Barrel Roll is wrong again.
