In all seriousness, they're both potentially good, but the first one looks too artificial (the metal finish doesn't help), and the second one definitely needs to have the beveling effect removed, and possibly some work done on the sword/crosses (they look pasted in). If made pure white and touched up, I think the second logo would be better. It has a much more BLACK METAL! vibe to it.
also, "Beneath the icy mountains, the only way down... is death. The only way up... is Satan." is genius
