are u talking about who would win between the nine-tails and lee or are we talking about who would win between lee and naruto? because theres no reason for naruto to get angry with lee, it would certainly be a fight between friends so no nine-tails chakra in the fight. PLUS the nine-tails chakra shouldnt be factored into this as its not really naruto who would be fighting, so imo if naruto and Lee fought it would be lee who would come out on top!
