While it ended in a tie I think there's a few factors that heavily point to Hit actually having more power than the current SSB Goku of that mini arc.
I already know some of the arguments against this that people have made.
My counterarguments for those three arguments would be:
With all of that considered while I don't think there's a huge difference I am very confident in saying Mini Arc Hit > Mini Arc SSB Goku in pure power and speed. The general trend from what i've seen has been that after the universe 6 tournament Hit's continued to be a SSB level+ fighter even with current SSB getting stronger and stronger as Goku and Vegeta train. Hit also trains so since he was above it after his improvement during the U6 tournament he's still above it now with his increases from training matching each increase to current SSB level Goku and Vegeta make with their own training. Current SSBKK and its multipliers are a different story but Hit can reach them with improvement like he did before if he does face them.
1. Almost every physical blow Hit landed on Goku had him reeling .
2. Hit knocked Goku out of SSB with much less wind up for his physical strike than True Golden Frieza did when he knocked Goku out of SSB with the Double KO. True Golden Frieza charged at Goku full force while Hit just cocked his arms back a bit and slammed down.
3. Hit had enough energy to fly all the way back to universe 6 after the fight was over despite taking a kamehameha from SSB Goku that drained him out of the form meaning he used every last bit of his energy and the multiplier for that kamehameha was higher than the normal multiplier .

1. "Goku didn't use kaioken blue which he would've done if Hit was stronger than his current blue"
2. "Goku endured Hit's attacks during the rematch and kept fighting regardless"
3. "The attacks were all aimed at Goku's vital points so of course they'd make him reel"
2. "Goku endured Hit's attacks during the rematch and kept fighting regardless"
3. "The attacks were all aimed at Goku's vital points so of course they'd make him reel"
My counterarguments for those three arguments would be:
1. Goku ALSO didn't use Kaioken Blue against Goku Black despite Black curbstomping him for the majority of the arc. He only finally resorted to using it for a kick against Merged Zamasu. Kaioken Blue is just too big of a risk if you aren't sure you can beat your opponent with it. In black and Hit's cases Kaioken Blue being used against them can actually make them stronger due to Zenkai and Improvement respectively.
2. Goku was only able to keep fighting because Hit's honor prevented him from attacking him while he was down. There were many opportunities during that fight where Hit could've continued striking Goku but didn't. There was one time where Goku was downed for more than a minute (When the fight was cut away from for Vados to explain timeskip and Hit's pocket dimension to Champa) but Hit still waited for him to catch his breath that entire time.
3. Back during the U6 tournament Hit struck SSB Vegeta's vital points with multiple barrages of punches during multiple timeskips but Vegeta could keep standing due to them being "light attacks". Hit ended the fight when he struck one of Vegeta's vital points with as Vegeta called it, a "heavy attack". Considering during the rematch almost every physical blow Hit landed had Goku reeling like the "heavy attack" Hit used against Vegeta (and Hit didn't even use timeskip like he did back then so Goku should have actually had time to react unlike Vegeta) it seems like Hit's physical strength and speed rose to the level where even his normal blows were like fast heavy blows to Goku. And the reverse did not seem to be true considering Hit could dodge Goku's counter punch and only get grazed. Hit could react and dodge Goku's counter punch from an extremely close distance whereas Goku couldn't seem to react in time to dodge any of Hit's punches during the rematch.
