Hmm, I think my post came out wrongly. I didn't mean it in that particular fashion.
I agree that Naruto/Sasuke have the best bromance. It's a complicated relationship, but it's both ways.
I meant it from the perspective of 'how it's shown" after they've settled each other's issues.
Gaara got a lot of opportunities to illustrate how his resolution with Naruto changed him, and in fact many Gaara scenes were dedicated to showing how much Gaara values Naruto as a friend. (his speech to Sasuke, his Alliance speech, etc ) Bee was introduced late, and didn't need any complicated baggage, but he got his chances to show both A and Naruto that he's a great bro.
Neji didn't. :/
Sasuke obviously doesn't get that privilege, because as the defacto bro/last boss of the series, he doesn't get to show his zeal much in terms of putting his fist out for the brofist, because his issues got resolved last.
