>>1827357It all comes down to naruto or sasuke
Let's take it a bit further and look at what both characters attempted in their fight.
Sasuke used all of the powers in his employ to try to kill Naruto (all in his employ as in all he had access to). Naruto used all of the powers in his employ to try to defend against the onslaught (Rikudou Sage Mode, the most powerful form any ninja can take in the entire manga. Naruto held back his actions, not his power). By that logic both characters fought as hard as they could. This is evidenced by both characters receiving injuries in their first clash (Susanoo Chidori vs. Bijuudama resulted in Sasuke losing a wing, and Kurama using half his face).
Evenly matched.
Next, Sasuke overcomes his limits to change the stalemate by pulling chakra from the bijuu. Naruto then overcomes HIS limits to keep the stalemate... stale by having Kurama give him more natural energy than he's ever had before. So much it takes all the natural energy from the current area. This is the second time during the fight where everything Sasuke threw at Naruto couldn't stop him, while Naruto managed to defend against said attacks at great cost to himself.
Lastly, they both are fighting even further beyond those limits, with barely any chakra. They're both failing to use ninjutsu, they're both either kneeling while tired, or falling over. Sasuke has the advantage here because base Sasuke is superior to base Naruto, but eye fatigue causes him to fail. Sasuke gets a moment of Rinnegan use to restore some chakra, and Naruto gets a moment of bijuu chakra from Kurama. They both throw everything they have left at each other, and they both lose an arm, ending the fight.
