Guessing

Don't know who Problem Sleuth is, but it should be expected to win.

🤔🤔🤔🤔

Problem Sleuth (All Forms)!

Helluvaverse

Ok I'm gonna actually explain things here, even if we use the universal meta for Hellaverse PS would still outstat them because he killed DMK who was universal on a greater scale. He also has holy weapons that negate invincibility and regen so killing the demons shouldn't be too much of an issue.

My hate for Hazbin hotel makes this decision undeniable….
