If you ask me, they're pretty weak. I'm so used to heavy stuff right now, most Grind has become light listening. An amazing song to headbang to: Raped By Elephants by Torsof*ck. I hurt my neck headbanging to that. Cannibal Corpse have always seemed pretty pathetic to me, to be honest. If you're looking for the upper boundaries of sound, then Harsh Noise is where it's at, like Masonna.
