I've said 3 years ago that Sukuna will use the 10s in some way in his fight with Gojo because Gojo is stronger than the og or heian era Sukuna. And that's basically been confirmed.
It's just that his hardcore fans ruin him. Firstly they don't get the character they stan. Secondly, they downplay Gojo constantly and consistently. We've been through the phases of 15 finger Shibuya Sukuna negs Gojo, then the fight started and it was ok maybe Gojo beats 15 finger Shibuya Sukuna but current Sukuna negs him, then Sukuna is just playing around, then when Gojo got slashed they said it was over and he died, then it was Sukuna will spare Gojo and turn off his domain, then it was no way Sukuna would ever use 10 shadows or Mahoraga, to the final phase now where it's none of that matters, a win is a win lol. When the entire 'conflict' hinged on who is actually the strongest on their own lol.
The banter is with his fans, and giving them the Ls they racked up lol. I said months ago that if Sukuna were to win against Gojo I'll be cheering for Sukuna then. Sure as hell won't be cheering for Maki and Yuta and the likes lol.
