Winner of first battle (Valley of the End): Sasuke

Winner of second battle (Kage Summit Arc): Undecided

Winner of third battle (chapter 698): Naruto

Sasuke managed to overpower Naruto in their first battle but by their second battle, they realized they were too equal to decide who would win. Same goes for their last battle, but by then, Sasuke had decided to give up his goal of starting a revolution and said he lost to Naruto. He indeed said "I lost" twice but they still consider each other equals.
