Toneri had somewhat the same Goal as Madara. Madara gained Hagoromo's Power and Toneri, Hamura's. The both powers are, I believe equivalent.
Sharingan >> Rinnegan = Byakugan >> Tenseigan
He who awakens the Rinnegan, shall receive the Powers of Hagoromo and he who awakens the Tenseigan shall receive the Powers of Hamura. Which is exactly what happened. BUT... Toneri had the Power of Hamura, who has the equivalent Power as Hagoromo... Then, how was Naruto able to finish Toneri's Tenseigan (and the Powers of Hamura) away with one blow?? + just in Nine Tails Mode, without his Six Paths Powers.. It just doesn't add up.
Now.. let's move to the Movie Boruto:
Kinshiki and Momoshiki are very powerful beings... Momoshiki even has 3 Rinnegan (One in his Forehead, and one in each palm) and has also the equivalent, if not greater Power to those of Kaguya.... how the hell was he defeated by only Boruto (a child)? While it took Naruto & Sasuke to seal away (not defeat) Kaguya and they both had the Six Paths Powers, while Boruto had none whatsoever.
