It's kinda weird. I've never been a Slayer fan. Mainly because the vocals never matched the music for my tastes. And King is a bit of a dick, so it wasn't worth it. I respect all their talent, but I just never liked the music despite their skill.
But this song works for me. Fucking love it. It isn't very different from Slayer, so I shouldn't really like it. But whatever it is that's different, maybe it's the vocals, I've been playing this a good bit since it came out. Great fucking song.
