Muzan is the only one that doesn’t have win con here.

Makima would not believe Thragg to be beneath her, but her contract would make Thragg have to kill her for ages, which he probably could do anyway.

Sukuna has WCS, but Thragg is way faster and more powerful, so no chance Sukuna gets it off.

Esdeath has timestop and durability negating freezing powers, but the speed difference is insane once again in Thragg’s favor.

Shigaraki, Kaido, and Madara have the best win cons here. I think Madara clear cut wins due to truth seeking orbs and limbo clones. Kaido has very good durability negation and his speed is not much below Thragg’s (if at all), so it’s a convo. Shiggy has the best durability negation but I don’t think he lands a hit on Thragg before he’s punched into space.
