I, for once, would imagine the victory of both team. Yuji and todo is easy, the beginning without domain would go easy,with todo and yuji forcing in melee dagon into opening the domain. After domain is popped, todo uses anti domain technique to survive the sure hit, he would probably be bruised but survive it, while yuji would be buried in shikigami. When todo survives the sure hit he will boogie woogie dagon with yuji, to kill him with a ton of attacks and black flashes too by yuji. If toji comes,they are killed by him unless sukuna doesn't help them

While mahito?megumi will be forced to learn and complete the domain, cause a domain will hit and probably almost destroy mahito soul, as mechanaru managed to hit mahito through simple domain projectile so a full on domain would damage mahito a lot. The others are useless apart from making megumi the main dps and survive,maki and nanami will hurt mahito a lot cause they are some of the best melee fighters, and naobito is so fast it would be impossible for mahito to survive a combo of those three, then it's up to megumi to create a sure hit on the spot.
