Whoa, whoa ,whoa. He didnīt topped anyone, he summoned Susaano and broke the fucking building. Absolutely no one died or was even scratched from it. No one of importance that is. Sasuke fled the battle scene, he didnīt won it.
He's had his umpteenth consecutive uber fight scene(considering how rarely Naruto gets to fight he should be a side character by action manga standards) where he topped all his previous ownages by beating two Kages and six elite Jounin all at once. The kind of author love Naruto can only dream of.
