Juubi's Chakra doesn't alter Madara's skill with his Rinnegan. The only thing that Juubi boosted was the raw power of the Jutsu. Not CT itself.
First slash: Nagato gets stomped by the Hokages, BSM Naruto and 7 Bijuu together. Madara used Limbo, a technique Nagato has never knew. Madara used the chains to bind their power, a technique Nagato never knew.
Second slash: Complete irrelevancy. Madara summoned the statue from the moon.
Nagato is FAR less potent with the Rinnegan than Madara, the real wielder. Nothing is going to change that.
Madara used the chains to bind their power, a technique Nagato never knew.
You're telling nagato did not know a technique that even obito knew?? Yes obito used that technique to bind Bijuus after naruto freed then from the black rod!
Juubi's Chakra doesn't alter Madara's skill with his Rinnegan.
It doesn't alter the skill but boost the jutsu power like hell! Didn't you know power also boosts the user to use different skill level. A Good example is Hashirama and Yamato.
Here are some facts!
Nagato used six paths Madara did not
Nagato used different fuin jutsus Madara did not
Nagato used Genjutsu Block Madara did not
Nagato used All five elements Madara did not
Nagato used Shinra Tensei Madara did not
Nagato used Banso Tenin Madara did not
Nagato used CT so did madara ~ his skill and jutsu level were higher bcos of being the juubi jin there is no denying this!
Madara used Limbo Nagato did not ~ why cos nagato was always in the shadows, his paths fought in his place.
Deva path could fly so could madara.
Madara could absorb ninjutsu so could Gakido and nagato
Nagato could summon various animals along with Gedo Mazo madara can only summon Gedo Mazo
Nagato used gedo mazo to seal bujjus so did madara ~ Madara could seal all of them togather bcos they were all at the same place while at nagato's period it was scattered all over NV
Nagato used gedo mazo to fight an army with the soul sucking dragon Madara did not!
The only real feat of madara with his rinnegan is Tengai Shinsei that is even in his edo form! (Unlimited Chakra)
How long did he fight the SA with his own chakra?? A few Panels only! Nagato took on the most powerful ninja village alone!
FYI: Omnyodon is not a rinnegan based technique, you get that power when one becomes the juubi jin!
Nagato is FAR less potent with the Rinnegan than Madara, the real wielder. Nothing is going to change that
So as you can see nagato has more jutsu and rinnegan feats then madara! It changes the whole thing Nagato is no less potent then Madara!
Like I already said Off-course the rinnegan suits better to the original user but Nagato was no less potent with the rinnegan!
