Controversial opinions on metal

Overkill should have been in the Big Four before Anthrax.

They're about equally deserving, both being bands that were among the fastest of the non-innovators to jump on the bandwagon. In a shoulda-coulda-woulda scenario, Exodus and Watchtower deserved it more.
 
There's no way Sepultura would ever find themselves opening a stadium concert with Antichrist in 1987. They lacked accessibility early on, and their straight-up thrash is derivative, crap, and late-coming much like most of Skolnick-era Testament.
