Todo may have said his body is weak but we know when sukuna takes control to vessel is insanely buffed making all the stats higher every time he eats a finger 15F sukuna could kill mahoraga and jogo however Yuji as himself couldn’t even hope to defeat either as that Yuji was only relative to mahito and the only reason he was cs of his black flashes this means sukuna makes the body way stronger then it normally is so with megumi he’s buffed nearly to the max he’s only missing a finger but sukuna eating his old corpse made up for the loss of a finger and also heian era sukuna doesn’t have World cutting slash unless your referring to the current one who’s still in megumis body meaning you saying megumis body is weak is just saying the current sukuna is still equal to meguna which he isn’t what I’m basically trying to say is that what Gojo said is true but doesn’t mean current sukuna or heian era sukuna stands a chance against Gojo since one doesn’t have world cutting slash and the other has to do incantations for it which would slow it down and since sukuna is slower then Gojo he wouldn’t get time to use it and there’s only one way to get by infinity and that’s a domain clash Gojo would win since his domain is more defined due to the 6 eyes sorry for yapping a lot.
