I mean Blackwater Park is definitely great. Personally I would put it just below those 4 I mentioned. While it does have some of their best songs (title-track, Leper Affinity, Bleak, Drapery Falls & Harvest), I feel like the rest just pales in comparison, and while I don't dislike Dirge for November or The Funeral Portrait, I would say they are 2 of the weaker songs from the golden era of Opeth. Meanwhile on Deliverance, Ghost Reveries, Still Life & My Arms Your Hearse, I think the lowest points are better and the higher points are still strong.
