Yes, we know that Nagato is extremely proficient in terms of ninjutsu and has many abilities which can pose a threat to Bee, but we know that if he taught Naruto how to do the chakra tug-o-war, then he should be able it to do it as well. Personally, I don't see much of a chance of how Killer Bee could win here but we know that even his base form can solo most characters. He has more skill in taijutsu and swordplay, but all of those ones predominantly require chakra, such as the Lariat. Should Killer Bee have Samehada equipped, he should be able to hold his own for while but one of his biggest disadvantages is any form of ranged fighting. Even if Samehada could absorb chakra, Bee would have an extremely difficult time trying to get close in on Nagato use it effectively. Should he enter V1, yes he would be more faster and more powerful and may give him a chance to close in, but then the summons would have the Rinnegan Link and defend Nagato. The only ranged moves Killer Bee can use outside his base form is the Bijuudama Bomb and the laser move he used on Suigetsu. If Bee enters V2 mode, he will have slightly more advantages because of his size, tentacles, chakra reserves and ranged ability.
Lets say Nagato calls out his summons, Bee can hold them off with ease along with the fact that he has the Continuous Bijuudama Bomb, he can use his tentacles to create an opening and then just blast Nagato away. Considering the fact that the Valley of the End is predominantly water-terrain based, Nagato will have to use up chakra slightly more to maintain balance on water or rock faces. Killer Bee has greater chakra control and reserves than Nagato since he is a Jinchuriki and he should be able deplete his chakra fairly slowly if he doesn't resort to using his strong moves at once.
Thanks for replying now the real debate can begin. It has been said multiple times that the only way to take down Cerebus is to defeat the user and as Killer Bee has no knowledge he would be wasting alot of chakra trying to take the dog down

and he would be kept busy by the Panda,Rhino,Crab and the Giant Bird summons. And while Bee is fighting the summons the Asura Path can fire multiple missiles and chakra cannons at Bee and the missiles are very powerful as seen here,

he could use this catching him off guard or the Deva Path can just use Bansho Tenin to pull Bee towards the Human Path and the Human Path uses Soul Removal to finish Bee. Also Nagato might not be a Jinchurki but he has a huge amount of Chakra as being an Uzumaki he possessed strong Life Force and even after he destroyed Konoha he still had enough chakra to fight Naruto, and if Nagato had wanted to he could of made the Chibaku Tensei he used on Naruto bigger and since this is too kill the Deva Path would put much more chakra into the Chibaku Tensei to trap Bee and plus he was fatigued as he used alot of chakra but was still able to do such a huge Chibaku Tensei

now imagine just how big the Chibaku Tensei would be if he was 100%.
If Bee does enter V1 or V2 his chakra would be absorbed by the preta path and it has been shown before in Bee's battle against Kisame that the more chakra taken from him Bee couldn't go V1 or V2 as stated here

and Bee's attacks are chakra based which the preta path would absorb as well plus if Bee gets too close Deva Path can use Banshon Tenin and stab him with his Chakra Disruption Blades and the other paths can all rush into stabbing Bee with their Chakra Disruption Blades like they done against Jiraiya

, then the Asura Path can just blast Bee with his Chakra Canon to finish him off.
Plus Deva Path would provide huge problems for Bee especially with his Chou Shinra Tensei or Chibaku Tensei. Also if Gedo Mazo is Summoned alongside the other summons it can deal with Bee like it done against Hanzo's men and the ANBU members with its Soul Dragon or its other powerful tech the Demonic Statue Chakra Blast to strike Bee down.Also Pain's attacks aren't elemental attacks so Samehada won't be able to absorb it's chakra, as Samehada has shown to absorb elemental chakra attacks,chakra flow attack or chakra cloaks.
