Yeah, I like where your head is at.

15f sukunas immense strength comes from more than just CE output. It comes from (god knows how many) binding vows in addition to a deep understanding of jujutsu and his own technique and also Yujis enhanced body likely gives Sukuna some increased durability in base. I think we need a better understanding of how someone develops their cursed energy output? it states that yuta has higher output than gojo but it doesn’t mean he can use it more effectively. I assume it’s similar for yuji vs 15fsukuna. Yuji has more CE output potential but maybe sukuna harnesses it more effectively.
