1) Let me ask you a question who would win. This Naruto:1) Same nebulous tier...lmao. Nothing nebulous about an ant and a F16 being on the same tier. All evidence points to Nagato being the ant.
2) The burden of proof is on you to prove that Nagato not being at full strength was relevant. "Fatigue" doesn't really cover the gap between KSM and BM, and Nagato still had enough chakra for Rinne. Your favorite method of chakra scaling literally puts Naruto above Nagato, period.
3) Edo Nagato wasn't mobile, but he has none of the health issues of anorexic people nor any stamina strain. We already saw what ET did for Itachi and Hiruzen.

2) I don’t scale based on Chakra Quantity alone. Chakra is a big component but there is also Chakra Quality, which Nagato has the Chakra Quality of the Duel Rinnegan which is > Juubi
3) He was brought back in his most emaciated form; the Grey Haired form. So he was effected by this, and that’s the whole reason he gets stronger when he absorbs B’s chakra and recovers
