What each of them is ranked on
1 win · Naruto Uzumaki · rank 5
The Seventh Hokage — shippuden
Inside Baryon Mode he outfights the strongest thing the sequel has produced, and the argument for fifth rather than first is what that costs: the form burns his own life to run, expires on a clock, and leaves somebody else to strike last. He also spent the entire series formally ranked genin — the lowest grade the system issues — and then became Hokage, the top of the same ladder, without passing the examination in between.

shippuden
The other half of every fight in the tier above him, and the half that brings the tools rather than the volume — the Rinnegan lets him move between the same dimensions Kaguya uses to escape, which is what turns those fights from unwinnable into merely desperate. Carries the identical paperwork problem to Naruto: never promoted past the entry grade, having left the village before any retest could happen.

What this does not settle
2 results, each cited, and the tally counts every one of them the same. That is its rough edge: a win at one side's lowest weighs as much as a win at its peak, which is why a level score goes to the latest result rather than to a judgement about which fight mattered. It is a record of meetings, not a ranking of its own.
The ladder above it is argued from everything either of them has been shown doing; this page is argued from these 2 citations.
Where the two disagree, the disagreement is the point, and it stays visible rather than being resolved by whichever of them happens to be on this page.
