I'm Curious about Heian Era Sukuna

So now that the mangas almost over, me and my friends had our finale and last ever debate about the whole Gojo vs Sukuna fight.

My friend mentioned how HEIAN ERA Sukuna would beat Gojo faster than Megukuna but to me this doesn't make much sense.

He didn't have an arguement while I said that Heian Era might win the domain clashes and such but he wouldn't even be able to pass Gojos infinity.
