did anyone ever given them shit for naming their album after the Amebix classic?
Not that I know of, but I do remember seeing a photo of them in the book Choosing Death (a must have if you haven't) where one of them was rocking the No Gods, No Masters shirt.
For me, Sepultura was pretty untouchable up to and including Arise. Morbid Visions and Schizophrenia are death/thrash classics.
That entire Brazilian scene was untouchable during that time... Sepultura, Vulcano, Holocausto, Mutilator, Sextrash and Sarcafago were, like above mentioned Beherit, doing it way better than most of what came afterwards.
