can we assume he has/or can easily adapt to it since hes already seen the DE and a handful of Gojos named attacks through Yujis eyes?
Also given what we know Gojo has to essentially one shot-ish Sukuna or spam a few new abilities before sukuna/maho adapts to them - i wonder if he has enough to edge him out - even moreso if he gains the next 5 fingers.
Depends if you're talking about adapting Maho, in which case I guess Maho himself must directly experience them CTs.
Concerning Gojo's techniques I guess 1000+ yo Sukuna knows about both limitless and the 6th eye.
Maho aside, I guess prime/20 fingers Sukuna still > Gojo, but it's pure fiction so far.
Anyway, I don't see him (Gojo) winning now. Sukuna's CT/CE output + his "limitless" knowledge about curses + Maho is just overkill imo.
Though 100% serious Gojo wont be a joke, even for 20 fingers Sukuna. Fight will be intense.
