I think NaruHina is definitely the least of the big 3 pairings. Like, I really don't understand what appeals. She's the least developed of the four characters, she has the least screen time, and she has the least interactions. I personally find her character unappealing, though I understand why people would like her. However, the whole "I'm insecure and weak and I look up to you like a celebrity" thing is boring. It'd only be cute if Sakura didn't exist and Naruto actually had some kind of soft spot for her which changed him, like Kyo for Tohru. But his soft spot is for Sakura, so NaruHina has nothing much going for it unless you're a Hinata lover who just likes the ship to make her happy.
SasuSaku (don't hate me) is much more interesting if a ship IMO. Sasuke is beautiful, Sakura is awesome, and it could make a really interesting combination that could work our if Sakura ever had a chance to try to bring Sasuke back. I saw some cute SasuSaku family pics and I just adore them
Not as much a my NaruSaku ones, but hey. Anyway, my point is there's much more substance and depth to have an interesting relationship, if Kishi ever decided to go deeper than Sakura's superficial crush. I mean, they actually have interactions and Sasuke cares about her; which is saying a lot for a brooding jerk. I can definitely see the appeal. Sexy, angsty, and downright beautiful if Sakura got to be the one who changed him. However, the focus the entire time has been on Naruto and Sasuke's relationship so whatever chance Sakura had to be the one to bring Sasuke back and form a deep bond is gone. A bond sure as heck ain't gonna be forged in the next twenty chapters, that's for sure
NaruSaku is just adorable. I can see how people could find it boring though. It's just so obvious that some people could get bored with it. My sister for example doesn't really ship anything, but she knows NS is gonna happen because it's obvious. It's all a matter of opinion. The NH and SS shippers don't have a chance but they just don't realize it because they're so biased by their love for their ships.
