Dual Rinnegan living Madara vs Adult Naruto

[DHOH]

It is kind of implied, Obito stated even with only one Rinnegan, the power was almost too great for him to yield.

Power doesn't always means chakra. Obito was literally half Uchiha and half Senju so handling more chakra shouldn't been a problem.
Old Madara and Nagato handle to Rinnengan without any problems.

 

[NarutoX28]

No. Madara was stronger than teen Naruto with half Kurama. But this is adult Naruto with full Kurama. Strip off the Rikudou buffs and Madara is left with PS and Naruto is left with full Kurama as their full power.
Full Kurama completely shits on PS in terms of firepower.

Yeah, I misread. Full Kurama isn't stronger than PS outside of the Bijuudama, but Naruto got significantly stronger in just his Base Form as an Adult, so he'd likely win.
