Basically you don't want any metal but you want some metal.
Erm. Try Vader maybe. His growls are different and understandable. Arch Enemy. Maybe bolt thrower. Dan Swano's solo project. Grave, Unleashed and other old school death is not deep deep growls and they're pretty understandable. Athiest?
Lamb of God?
Oh yeah. And maybe early Deicide. on new deicide he sounds very Nile/Cannibal Corpse-ish but on the old stuff he's ace.
