Personally I like the two characters even if I prefer Gojo and I find that Gege handles the Sukuna case well. You can't give him a technique out of nowhere that can counter infinity, I would find that so ridiculous and much too easy. Gege had to remain consistent with what he created, he did it well with the territory duels where Sukuna, whatever one could say, had the advantage (except at the end) it was one of the means to counter goatjo's infinity now that both characters no longer have the ability to use this they are forced to just use their occult technique. And the only way Sukuna has left to counter infinity is Maho. I'd rather see a struggling Sukuna take hits in order to adapt to gojo's infinity than to learn that Sukuna actually had a technique that could counter Gojo's infinity, but that would be so lame and inconsistent
