The best Runemagick stuff is the two first albums, when they turned doomdeathish they became alot more boring imo. The first two are great swedeath with lots of atmosphere though.
That Ackercocke album is superb! They dissapointed me with "antichrist" though. Its pretty good but they added about 3 or 4 tracks which are of a lesser quality that unfortunately drags it down a couple of notches for me.
