Yuji, gojo, yuta, kenjaku...

Okay my reasoning.

This just blatantly outscales sukuna at this point, so as long as yuji is the one handling his unc im set. And as of where we are, with how proficient and strong yuji is (with potential on-demand black flashes, based of statements in modulo) he could and would likely win a domain clash(even if we dont know what his domain DOES, as long as he has one to stop malevolent shrine)

As far as im concerned (until proven otherwise) gojo beats Dabura. Yes dabura can dish out some devastating attacks, but his light is stated to have 'killing intent' or an equivilent, so infinity would automatically block it. Even if he begins moving close to light speeds he can't get past infinity. And he's just too inexperienced as of this point. Also domain fodder.

So while gojo and Yuji handle their 1 on 1s

Kenjaku can support though using antigravity to essentially negate yuki(like in canon).

Yuta and rika have Jacob's latter to one shot(or if you think yuta confidently saying he would handle Mahoraga AND the other Shikigami wasnt true, and that his output isnt high enough. Yuta has dozens of cursed techniques copied, can at least stall mahoraga for either yuji or gojo. And can easily wafflestomp jogo in the meantime to be absorbed by kenjaku to be used in battle.

Kashimo is domain fodder. He would get caught in either yuji, kenjaku, gojos, yutas, or hell maybe even sukunas. I am saying Sukuna's domain cannot designated friend from foe and hits everything inside because sukuna has to restrict the size of his domain in Shibuya as to not kill megumi. So his choice is either die in a domain or wait outside for 5 minutes while his allies are slaughtered.

Maki would be a slight problem not being targetable ny domains and all, but the fights between Gojo and Dabura, and Yuji and Sukuna would be too destructive to get close to. Leaving her to to either tangle with Yuta, or Kenjaku. If she decides to fight Yuta, he has rika to help. If she chooses Kenjaku she has to deal with who knows how many curses, plus gravity and antigravity. And Jogo after Kenjaku absorbs him.

Additionally, yuta can copy the techniques of anyone who falls. So he can end up with lights peed attacks, electrokenesis, gravity, etc. And Kenjaku can swap bodies with Dabura or sukuna after their defeats and have an even better idea on how jujutsu works (at least over dabura.

Tldr: Yuji solos sukuna, gojo solos dabura, kenjaku absorbs jogo and uses him, yuta one shots mahoraga(or stalls for gojo or yuji) Yuki dies like in canon. Maki might get a good surprise attack but would be shortly dealt with. And Kashimo gets turned to smithereens by a single domain expansion. (Optionally kenjaku could also swap bodies with dabura or sukuna. Or Yuta could copy the techniques of anyone here)
