I figured that both of these recent manga/anime antagonists are the midst of their respective final battles. So it's pretty good time to toss them at one another to see who comes out on top. And the discussion can kinda evolve as the manga battles go on.
Shigaraki: He has his perfected superhuman body and all the quirks he's displayed since his awakening. Tomura is in charge rather than All For One. For this battle he can see curses and interact with curses as well as jujutsu sorcerers.
Sukuna: He starts out as he did during his battle against Gojo. So he has his own abilities, the Ten Shadows and the ability to incarnate to his original body. He'll also have the cursed tool Kamutoke.
The battle takes place in Tokyo.
Which villain wins?
