You can see it in 2 ways.
he lost his sharingan and isn't able to see through attacks, he lost sharingan genjutsu ability and the feared kamui,
or now he has much more chakra, is able to preform more jutsus, has better stamina, can do more clones( shadow clones, ration clones, water clones....), has his normal eyes back which means he isn't handicapped, he need not to suffer after powerful jutsus ( after every kamui his body went through a lot of) and he can spam more of his other dangerous attacks like ration beast runner.....
I think he will show that he is still powerful and now he can fight without suffering
