Yeah, Pantera formed in 81, but by the 90's they dropped this look:
They were embarrassing themselves looking like that in the 80's.
FF isn't for everyone, i personally love the thrash/industrial sound they produce. Makes sense as i'm a huge Slayer fan, but also enjoy industrial type bands like Ministry as well.
There's some great stuff out there after the 80's. Some really talented musicians who've evolved metal to the next level (some good, some not so good). Don't let the limp bizkits of the world cloud your view of the scene. Disregard that garbage and others like it, there's plenty out there that may appeal to you.
