For sure Rinnegan is better than Normal Sharingan. But I doubt it is better than the EMS in the case that you have the MS sharingan technique to be intangible plus Susanno, Amaterasu, & Tsukyomi. I am not talking about an evolved Rinnegan which can already use the Sharingan's techniques but the one Pain had.
I disagree. The EMS has the most extreme power the uchiha can have however the rinnengan invariably has the power of the uchiha and the senju. The way I see it it is an inherently greater power capable of achieving much more. Heck, the rikudo was actually able to use the rinnengan to create things with izanagi, I don't think it is actually possible to surpass creating things out of nothing. More so, we really don't know if nagato was actually unable to use susanoo. Perhaps he simply never knew that was possible as he did not go through the sharingan phase madara went through. Obviously who the user is would make a huge difference however I would think the manga right now has pointed to the rinnengan being in general the most powerful doojutsu.
Also, why would we assume nagato was not some sort of genius? Jiraiya held him in very high regard and even with mobility problems he almost got the best of itachi, bee and naruto. Without those mobility issues who knows what would have happened in the fight. It does seem like nagato did not use the rinnengan to its full potential even in life (perhaps he had too little time with it considering any real training he could do must have been severely limited once his legs were destroyed).
nagato's body was weak so he simply relied on the six sage paths of the rinnegan through corpses and developed his rinnegan to do so.. he didn't included the sharingan techs into his eyes either he was weak to do so or was simply unaware of rinnegan's complete powers.
tobi is simply using rinnegans powers and he cannot develop these eyes that's why he had to give it to nagato to develop it.
besides itachi(MS),naruto,bee (two jinchuriki's). had tough time against rinnegan's sage of six paths so clearly nagato's rinnegan is powerful than MS and will be aganist EMS(note: ems is not a huge boost it only gives eternal light and removes the excruciating pain from the user when mangekyo is used plus tranplanted mangekyo sharingan's any additional powers in short two sets of mangekyo sharingan's powers so double heade susano is possible..)
Mobility problem is questionable once he was under Kabuto's control. When Nagato was free to an extent, he couldn't do anything without Itachi but once he was fully under Kabuto's control, he could move on his own.
But I do think Nagato didn't use his Rin'negan to its full potential. We rarely saw elemental attacks from him.
I personally never thought this was much of a question. With Nagato display of the Rinnegan and Jiraiya stating that the Rinnegan was said to be the strongest of the three doujustu i thought this question didn't need asking. But i'm glad the recent chapter has made it clear to the doubters.

That shows otherwise. Nagato was lacking in mobility throughout the fight.
Kabuto's statement really means little to me seeing as how we saw Nagato move on his own, pretty quickly, when he couldn't move at all while he had some freedom of mind. Up until Itachi Amaterasu'd him, Nagato had no mobility whatsoever, if any, and after Kabuto controlled him fully, Nagato was able to run and even catch Bee and hold his and Naruto's weight.
Yeah, that statement is weird considering we literally see Nagato run right up to Naruto after being fast enough to jump down behind Kirabi after previously being some distances away in front of them all. Nagato was by no means limited in mobility.
I would think there is a difference between nagato gaining some mobility and him being at his prime in that particular regard. The way kabuto phrased things it is clear that even with the boost he was not at his best.
Lacking mobility is different from not being mobile as he once was. HIs speed was the same, if not similar, to around the time he saved Konan. Kabuto may just be tryin to avoid blaming himself since it was kinda his fault Nagato got sealed away.
Nagato didn't even walk against Naruto and Bee: the Chameleon spit him in front of Bee and when it grabbed Naruto, it put him irght in front of Nagato.
Although I never understood how he could be limited in that regard: he could grow robotic legs or robotic arms like Dr. Octoganapus.
Nagato did walk against Kirabi and Naruto. Kirabi was the furthest one away from Nagato, yet after being blown away, Nagato was fast enough to jump down on his feet behind him.
After absorbing Kirabi's chakra and knocking him back, Naruto is caught some distances away and we see movement lines from Nagato running up to him.
Nagato may have taken a step to reach Naruto and grabbed his soul to support himself, but against Kiranabi, nothing indicates he actually made the jump: it's much more likely that the chameleon jumped and he fell from his mouth.
Nagato falling makes no sense seeing as that would mean the chameleon was fast enough to run completely in front of the Shinra Tensei blast. Not to mention Nagato landed on his feet and steps backward. And seeing how Nagato was standing for most of the time, he didn't need any help supporting himself.
