I feel bad for accidentally bringing Lamb of God and Gojira into this. It was intended as a joke, and never to compare anything. I mean, how
can you compare them? Totally different styles of metal from different time periods. Is Opeth better than Slayer or Megadeth? How about Amon Amarth? What of Emperor, or Immortal? Hell, even Black Sabbath? You can't compare. It comes down to opinion, and well, you know, that's just, like, your opinion, man.
Anyway, back to the big 4:
SLAYER NEEDS MORE HELL AWAITS IN THIS SET, and

TO WORLD PAINTED BLOOD OPENING EVERY GODDAMN SHOW IN THE LAST 2 YEARS. /rant
