It doesn't matter if those were Nagato's eyes or not. The rinnegan doesn't have the close to details attention property as the sharingan. The rinnegan doesn't have sharingan abilities.Madara was the only one to have ever distinct a clone from its user and maybe that was also because of his sensor abilities. Even Obito who had his fair share of sharingan experience couldn't distinct them apart.

Like I said, “…Either that or Madara is just a prodigy.” And it actually does have similar (if not more enhanced) analytical abilities than the Sharingan. For example: The Rinnegan is capable of visually seeing chakra flow in the environment while the sharingan cannot. But the exact details of the Rinnegan’s usage varies per wielded so it’s not consistent.

Just because Madara could differentiate Hashirama's clones doesn't mean anything. As matter of fact if too much chakra is focused on the main body, Wood clones easily lose their potency. Check 4th Great Ninja war for reference. So yeah unless you prove otherwise its not applicable to shadow clones. Just for record even Kaguya couldn't differentiate the clones from real one.
IT was painfully obvious to everyone by than. His chakra amount was too low for that Naruto to be actually the real one.

BZ verifies that Using Rinne Tensei causes the user's death which is later bolstered by DB.

I’m not doing individual quotes, I’m on my iPad; give me a break. I’ll just respond in sequential order:

Actually, because Madada could differentiate between Hashi’s wood clones it does mean something. Hashirama has an enormous amount of chakra therefore and his clones were so perfect. “Wood clones easily lose their potency,” Yeah unless you prove that, your argument is destroyed. FYI, Kaguya’s an idiot.

Painfully obvious doesn’t discredit Madara’s ability to differentiate.

So yeah its not at all perfect. Shadow clones are much more perfect and perhaps superior in terms of differentiation. So yeah my argument isn't destroyed. It's pretty clear Madara strains the real Hashirama to usually figure out or Chakra concentration. It does discredits Madara's ability. Just because Madara could predict Hashirama's move is just a psychological advantage at best.
Edit:I will remove link later on my own.

I couldn’t watch that video in my country but those were weak Edo Tensei clones. Orochimaru didn’t resurrect Hashirama at full power but even with that, Hashi could still control himself. But that’s besides the following points: 1.) Madara blatantly saw Hashirama make those Kage bushin so you didn’t disprove my statement. 2.) Those wood clones were up against Madara with the Rinnegan and Hashirama’s own power. As Kabuto called him, “the perfect fusion. The ultimate edo tensei. So Hashi’s clones wouldn’t have won anyway.

What? Without seeing the video how can you make these points. Besides Your perfect fusion did lose to Hashirama during the war so void point.

Lmfao he didn’t lose to him during the war, Madara threw the fight. He didn’t use any of his Wood Release nor Rinnegan abilities against Hashi so like it or not, he was holding back. Their battle was simple for nostalgia. So your point is void.

Yeah just like that Hashirama was pinned with black rods? Just like that Madara was using pretha path. Just because you feel that way doesn't mean anything here. Madara was going to be sealed. HE lost that fight for all practical purposes. Also Madara's wood release would be countered by superior ones from hashirama.

That was after he got revived and he didn’t use the preta path against Hashirama when he was Edo Tensei. Lmfao you’re failing so hard right now. So again, you illiterate dunce; Madara was holding back in their Edo Tensei battle and threw the fight.

Lmfao and more talking without proof but I’ll humor you. Even if “ Madara's wood release would be countered by superior ones from hashirama,” doesn’t change the fact that Madara restricted himself from using it therefore, invalidating your theory. So again, fail.
