I seriously doubt there was a band meeting with managers and label big wigs all gathered to discuss Anthrax trying to sound like Pantera. There's no question that Anthrax's chief songwriters were influenced by Pantera. Nothing wrong with that. Pantera was metals answer to anti-glam/hair band sentiment and grunge/alternative music that was dominating the airwaves at the time. Face it. The 90's happened. The bands that refused to conform are in relative obscurity now or defunct.
