Neji vs Hinata , it is not really my favorite , but it is really emotional . specially in the anime , the soundtrack that they made for it (Hinata vs Neji OST) hits the feels

it's really fits well with the characters (Neji and Hinata) backstories
(BTW listening to this after Neji's death makes it even more sad)
