It is necessary for Sukuna to have a free heal to start round 2, in TF Sukuna has 10s but he still needs a free heal, meaning that Gojo has to hit him with UV or Sukuna would just win the Shinjuku raid due to keeping domain and RCT, so we are left with Gojo landing UV on TF Sukuna and Mahoraga just breaking the domain, Heiankuna has no Mahoraga so he will die.

  
This is consistent with Sukuna's strategy which is to save TF because it's better for him this way, if there are circumstances that would make using TF better he would have done so, beating Gojo without getting nerfed would almost guarantee a victory and he already admits UV is difficult to handle, so he acknowledges the risks of fighting Gojo, so if TF was that good he would have used it and taking into account Gege's statement TF would have pushed Gojo to using a more creative strategy 

  
The last statement is Gege reaffirming the narrative that Sukuna shouldn't use TF early which means he won't get better results if he does so

  
It's very consistent with the narrative that Sukuna shouldn't use TF again Gojo so the logical conclusion we get from that is Sukuna gets hit with UV 

  
This could also be used to debunk DA arguments because if he could have won with DA as Meguna then the heal isn't necessary 

  
Tbh it doesn't prove Gojo > Heiankuna because Heiankuna has tools but i suppose it proves Gojo > Heiankuna with kamutoke only 

  
I don't believe this arg tho

Gojo > Heiankuna arg
