I think Dark Tranquillity took the title with Damage Done. In Flames held it during the TJR/Whoracle era, although both bands were excellent, In Flames achieved more recognition. Colony and Projector were both much lower than the bands previous albums. Clayman was better than Haven, and at this point I thought DT would not be as good as they ad been. Damage Done was much better than Reroute to Remain, and that is when DT took the title from In Flames. Here's a quick look at the other bands:
Dimension Zero - Not realy active enough, but 'This is Hell' should be excellent.
Arch Enemy - A great band, but haven't been above The Jester Race and Whoracle back then, and ow Wages of Sin isn't as good as Damage Done.
Soilwork - They suck, that's it.
