I think the chainsaw Devil is stronger then the Darkness Devil because he fought the 4 hose men and the weapon Devils by himself but the Darkness Devil only fought makima and got hurt. But all the love ❤️ still.
Chainsawman fought all those devils and got severely wounded and ran away. Darkness fights Makima, is wounded and nearly kills her with the blade. She’s only able to land one hit to begin with lol. Basically she scratched him enough to just make him want to one shot her
