It's unclear just how fast he is now. His base looks to be the same as Minato now. Taking that speed level into consideration, in addition to all large number of OP shadow clones and multiple massive rasengan barrages (I sincerely doubt he can throw a rasenshuriken in base, that's dense heavy chakra). And summonings still provide him a lot of support (his base is still pretty basic to be honest, shadow clones and rasenagan, but with shunshin now). (Is base Naruto a sensor?)
I'd say he can beat:
- Every Hokage (including Danzo) except Hashirama BM Minato and DMS Kakashi
- Every Akatsuki (including pain and orochimaru), except for Nagato
- Every former Kage (I'm positive he'll take down third Raikage in base)
- Ever current Kage
- He can take Guy in 7th Gate
So he can't take: Killer Bee, Madara, Kabuto, Nagato, Hashirama, DMS Kakashi, BM Minato
And this is based on me not knowing hardly any of base Narutos abilities. And I'm not considering rikudo power ups as his base.
