So I think that gojo wins against hein era sukuna if he puts away his pride in the sense that he doesn't enter unnecessary domain clash with sukuna. 

If gojo maintains his distance from sukuna and keep in spamming hollow purple what will sukuna do , sukuna can't force gojo to enter a domain clash since gojo can use blue to teleport out of range , since gojo would know that through six eyes when sukuna is about to open his domain he can instantly teleport out of range through blue then after sukuna has to cancel his domain , he will suffer from burnout then gojo can use unlimited void and its gg.

Then sukuna can use domain amplification to enter a traditional fight in which again gojo has a huge advantage , sukuna wouldn't be able to use cleave and dismantle in his domain amplification and it also burns his cursed energy gojo while having his ct also have virtually unlimited cursed energy eventually gojo can just tire sukuna out or even without he has a massive advantage over sukuna he can keep spamming hollow purple while keeping his distance appropriate one using blue. Blue just take a handsign and gojo can use binding vow sacrificing something small to remove that limitations so like sukuna has it seems to be very less chance if gojo keep his pride in check and use this strategy 

What do you guys think

Hot take: Gojo beats sukuna if he puts away his pride
