It's important to understand that Chuck Schuldiner was a fervent homosexual who spoke with a heavy lisp as is often the case with enthusiastic homosexuals. This extremely noticeable lisp compromised Chuck's vocals quite severely and is part of the reason Death are often described as "prog metal" or even "death metal for people who don't like death metal."

I would certainly suggest listening to other extreme metal bands before writing off extreme metal vocals entirely.
