Heritage is always going to hold a special spot for me because of it's immense atmosphere and direct link to the gorgeous Storm Corrosion. But I definitely like Sorceress more than PC. Granted, that isn't saying all that much because while I don't dislike PC, it's just kind of "there" for me. I don't listen to it much, I don't get dem feels, it's just...an album. I do get some feelsy feels with certain moments in certain songs on Sorceress but honestly I prefer the more atmospheric and ambient side to the "new Opeth". That said, there are some great moments like that on Sorceress, and therein lies my cautious love for it.
Among the rebirth trio, Heritage still reigns supreme in my eyes though.
