Neji wasn't using the byakugan for the registration section. I'm fairly certain he would have seen through it.Originally posted by: Copy Ninja
They both seem pretty bad ass, but it also depends on how good the user is w/his advanced bloodline. I like the Sharingan a little better, because it seems that Neji was unable to see through Genjutsu when the first unofficial chuunin test was performed. Sasuke saw right through it...and Neji can't see through the clones either when he was fighting against Naruto.
As for seeing through Naruto's clones, Kage Bunshin is a special case. It is a high-level jutsu that splits up the user's chakra evenly so that you essentially have a bunch of Narutos at the same fighting power. On the other hand, regular bunshins probably create a much weaker copy of the original. Remember, Zabuza's clones only had 1/10 of his strength.
I get the impression that Neji's byakugan sees chakra in all its forms. It would be easy to tell if someone was performing illusionary techniques.
I tend to think of these two skills as evenly matched. They're both awesome. The byakugan is the ultimate defensive vision, whereas the sharingan is a bit more offensive. Byakugan detects any attack coming at you, lets the user scan ahead long distances (2nd exam), and allows you to see through things (looking into Shino's body at bugs).
Sharingan is offensive because it lets the user copy skills. But it also lets the user see things in slow motion, and has the ability to scan things to a lesser extent (Sasuke saw through those illusion clones that Naruto was fighting in the 2nd exam). But sharingan doesn't let the user see in 360 degrees or detect every attack coming at him.
BTW, I am don't think I'm spoiling, cuz I don't read the manga, and any spoilers I might have given are from at least 10 episodes ago [img]i/expressions/face-icon-small-smile.gif[/img]
