Re: VS Thread [With Manga Spoilers!]
We don't know all of Kurenai's abilities, but she is probably strong (since she is a jounin). I think she would win against chuunin exam Neji because Neji was very unstable at that time and he would probably make a mistake of underestimating Kurenai, but Neji from the rescue Sasuke arc would win because he was more mature then.
This is all going on the assumption Neji would be good at defending against genjutsu.
In first case Neji would defend against a couple of genjutsus and then get all arrogant about byakugan thinking he will beat Kurenai with just his foot. Then Kurenai would win because she has other skills as well since she is a jounin and probably knows how to counter byakugan somehow. The other case is where Neji is mature enough not to underestimate her and keeps his guard up so he deflects all her attacks and wins.
The great off panel war has begun...also called the war of one panel because most fights started and ended in one panel.
