No evidence Goku wasn't stronger in their second fight. Especially since Goku drank the literal magic divine water prior as a powerup in order to fight him in the first place.
>Tao Pai Pai
Goku was much stronger than him in his rematch. Tao Pai Pai was kicking himself over how Goku was too fast. Goku tanked his full powered barrage and got up without much issue.

Goku forfeited. Hit was getting overpowered by blue kaioken x10 and then Hit took the advantage back through adaptation and still mogged Goku. Then there's the case you mentioned where Hit couldn't use his killing moves ie he was holding back anyway.
