Lee would win if he had the chance to activate ALL gates even then he will be left in a ND state and Neji might still be alive (Kidomaru's incident) the question is; Can Neji survive all of Lee's gates? If yes then Neji wins. Lee will be completely paralysed and vulnerable to anything Neji does, ie: Gentle fist chakra palm. To finish the job
It's simple minded people like you that make me angry, it was Naruto's chakra cloak that gave him the strength without that he would've broke his leg and considering Madara couldn't dodge because he was tied down to the 10 tails I would never think any would think; Lee>Edo Madara.. *SMH*
