All that I say is, read the manga...

Joking...

I love Lee too as you all do, but I believe Neji would won... It is not a physical barrier as that of Gaara...

It is an energetic shield... I mean, it deflects anything within the 360 degrees...
It is a supreme defense technique, he manipulates his chacra energy to deflect any flying or not object in his direction...

It is far superior than Gaara´s and would just blow Lee away, and as manga shows, he uses it far more times than people here think with the a far consuming chackra...

You have to understand that Hyuga Bloodline as shown seems to be superior of the Uchiha that is so feared... And Neji seems to be the greatest light within this clan, so possible he is the best user of Chackra in the whole Konoha Village...

I touched the manga subject, but there is no spoilers I believe... I could give more details, but then it would really be a spoiler...

When I say "manga", is more like, be ready for more amazing things, and indeed, it is no dbz...
