The DB stats are fine. Kurenai may be a 5 in Genjutsu, but we all know that Itachi is beyond a 5. But it's not a big deal no worries.
Neji would outlast Sasuke though, that's the thing. In Neji's fight against Naruto, he outlasted Naruto, until Kurama got involved, and even then he was almost the last one standing until Naruto pulled that slick sneak attack. Sasuke vs Naruto can't be compared here, because Sasuke had CM, which is restricted here. And as you know CM gives Orochimaru's own chakra to the victim + Natural energy.
Neji did outlast Naruto though. Base Naruto's chakra reserves we're big indeed, but the way he used his clones, and basic arsenal is what depleted him so quickly that's the thing. Neji was finesse the entire match. It was like Sasuke vs Itachi. Itachi made Sasuke use all his chakra taxing techniques until he had hardly any chakra left over, and Orochimaru took over, while Itachi had a substantiate amount left enough to sustain Susano'o, and pull out Yata Mirror, and Totsuka Blade to seal Orochimaru.
I also disagree on the statement that 3T gives Sasuke the advantage. Byakugan's perception is much better, and even has precognition as seen here:

"Can sense all of his opponents attacks."
Byakugan in my honest opinion is slightly superior to 3T Sharingan.
