I equate how good Naruto is to the fighting in that arc. Kage summit had amazing battles so I dont see it far off from the pain arc. Obviously the pain arc was set on a bigger scale which makes it overall seems better.^This
The arcs after like the Kage Summit weren't shit, but you could tell that it wasn't on par with the past arcs. Bit by bit it was becoming worse and worse. It almost seemed that Kishimoto didn't even know what to do at times, his writing felt very awkward and bland.
