Tbh aside from Carcass /Regurgitate/Exhumed, I've never really gotten into it. Grind influenced music tends to substitute ferocity for atmosphere in my experience; it lacks the oppressive/evil vibe of straight up death metal. I'm willing to rethink that position on an artist by artist basis, though,
Dno exactly what genre you'd classify Mortician under, but imo they bring together the best aspects of grindcore and death metal.
