Neji would win! A Genin at the start of the series, Hyûga Neji is the #1 rookie of his Ninja Academy graduating class during the first several volumes of the manga. He is also considered to be the strongest and most talented of all the Konoha Genin who attended the Chûnin exam during that arc, and is the first of them to become a Jônin. Neji has a very powerful long-range defense in the form of the Hakkeshô Kaiten (Eight Trigram Palms Heavenly Spin), which is only passed down within the Hyûga main house but which Neji learned himself, and a deadly short-range offense in his natural proficiency in the Leaf's strongest taijutsu style, Jûken (Gentle Fist). To augment his short-range offense, Neji uses the Hakke Rokujuyon Shô (Eight Trigrams Sixty-Four Palms) maneuver (and, in the anime, also Hakke Hyaku Nijûha Shô (Eight Trigrams One Hundred Twenty-Eight Palms)) which effectively seals off a person's chakra points, rendering them completely unable to channel any chakra. However, his Byakugan does not have a complete 360° vision due to a blind spot located behind his first thoracic vertebra.
Neji is in the same Genin team as Rock Lee, Tenten and their Jônin sensei Maito Gai. Neji and Lee have a long-ongoing rivalry, which, not unlike the rivalry between Gai and Kakashi, mostly comes from Lee's side. Lee, who has been fighting against his fate as a worthless shinobi all his life, tries desperately to prove himself to the world in general and Neji in particular. Neji has mocked Lee's dream of becoming a fine shinobi in the past, saying one cannot go against fate, but after Neji's defeat by Naruto, he seems to have warmed up to Lee. Tenten is often seen sparring with Neji, which usually consists of Tenten honing her skill with throwing weapons and Neji deflecting the weapons with his Hakkeshô Kaiten. The two of them are often equally annoyed with Lee and Gai's overreacting and childish behaviour, but are similarly equally dedicated to fighting for their teammates. Despite his rank, Neji still goes out on missions with his team.
Despite his mastery of Jûken and Byakugan, Neji can never be the leader of his clan because he is a member of the branch house, his father, Hyûga Hizashi, having been born into the world after his uncle, Hyûga Hiashi, even though they were twins. In his childhood, Neji had nothing against the main family as he was probably being too young to fully understand the implications of being a branch family member, but as he grew up seeing his father feeling nothing but hatred for his own brother and the main family, he gradually came to resent it himself. His resentment only deepened as he witnessed his father enraged first hand while watching Hyûga Hinata, Hiashi's elder daughter and then the destined Hyûga main family heir, train with her father; for he knew that his own son, Neji, will never be the heir of his clan. Detecting Hizashi's vibes of animosity, Hiashi activated the Juin (Cursed seal), putting his brother in immense pain as his nerves were being attacked. It was Neji's first encounter with the Hyûga Curse Seal.
It was not until the incident with Kumogakure (Hidden Cloud)'s and Konohagakure (Hidden Leaf)'s peace treaty, however, that Neji truly became who he was when he showed up for the Chûnin exams. The two villages, which were at war with one another, apparently decided to sign a treaty, and for this representatives from Kumogakure arrived. On the same day, the very same curse seal that tortured his father was put upon Neji himself; and that night, the ambassador from the Lightning country attempted to kidnap Hinata, revealing that the intention of the "treaty" was all along to get into the Fire country and acquire the secret of Byakugan. Hiashi detected the intruder and killed him at once, for which Kumogakure, absurdly, requested payback in the form of Hiashi's dead body. That day, Neji's father was sent to his death instead of Hiashi, and Neji grew up believing that his father was sent against his will to protect the Hyûga clan's secret bloodline.
This chain of events drove him to the point of believing that destiny, a person's future is decided from birth and that there was no way to escape or change it, making him a particularly bitter, cynical and arrogant character with a spiteful grudge against the main house.
