Something like that can only be an opinion not fact. And I don't agree with you in the least. He's technically excellent, but he does little for me. And how is it even a relevant topic on the In Flames forum?
Borknagar are a shadow of the band they once were. Their debut album (or even The Olden Domain) is much better than Empiricism or Epic.
Nice list of bands. Dimmu Borgir's best album is Stormblast in my opinion. I'd actually say that PEM is one of their weakest. Old Man's Child aren't that good, kind of like Dimmu Borgir with weaker songwriting. The new Cradle Of Filth album? Well, it's better than the last one, but it's just not enough to keep me listening to that band. From these bands, spend all of your money on Emperor, Satyricon, Immortal, Dissection and Gorgoroth. You will NOT regret it. Marduk and Dark Funeral are pretty cool, too.
