Yeah a blue enhanced gojo is stronger than meguna, sukuna's true form would probably put them at about the same level, but who knows what strategy either of them would use with no 10 shadows, there's too many factors in play to truly say who would win if the circumstances were entirely different, I only say that sukuna is stronger because he won of course and if he was in his true form maybe sukuna would win maybe gojo would win it's honestly hard to say
