High Jounin to low Kage at best.
- Learned Multiple Shadow Clones (A-Rank), Rasengan (A-Rank), and FRS (S-Rank).
- Kakashi already compared FRS Naruto to roughly himself (MS-less). At that time, his FRS was at best 50%.
- Naruto's Chou Odama Rasegan forced V1 Madara into upping his Susanoo. Yes, it was in collaboration with others, but very few jounins have jutsus that can do that.
- Naruto was dead equal to Sasuke in CQC. Then he was able to send him towards the waterfall with base strength alone.
- Also has decent speed, reaction, and body flicker.
Then there's him being years older, so logically he should have improve greatly.
