I will try to answer in a way I can imagine their relationship in the future, from a NH perstective. This is very hard to do, because when I wrote this, it was hard to portray the pairing as deep and realistic. But I will try : D
NaruHina is a very easy pairing, their relationship is very un-complicated. If Naruto and Hinata end up together, they'll live IMO live a very simple A4 life. Minor arguing, Hinata would be of service to Naruto everyday(615 proved otherwise, but it is not enough), as she has a "live for Naruto, die for Naruto, everything for Naruto" way of life. This is her lifestyle. Do I like it? -

NaruHina is a very easy pairing, their relationship is very un-complicated. This may be taken a flawless relationship for the NH fans. NS more like my taste, because they've grown together, been through a lot together - together, together, together.
I think many people that are NaruHina fans(the boys) would want Hinata as a girlfriend themselves. They think she is flawless, and would never be heartless or violent to her lover. Many arguments says Hinata would treat Naruto right. "Hinata deserves Naruto" "Hinata would never hit or lie to him". Maybe they think Naruto deserves this "perfect" woman because he's had a hard past. The same goes for Hinata, she's had a hard past, so she deserves him.
Ah, I've heard of that before. Hinata is the ideal woman for some men - shy, quiet, and submissive... Apparently a lot of guys are into that.
Personally, I just don't see the chemistry between her and Naruto. It's like you said, they would have a very simple life together, but there's something missing in their relationship that NaruSaku has. The whole togetherness. I don't even know how to describe it myself. They suit one another. They've gone through nearly all of their experiences in life together.
Also, like
kirabook mentioned, I've never viewed Hinata winning Naruto as a big achievement. Perhaps it's because I've been rooting for Naruto this whole time, or perhaps it's because I still see her feelings as superficial. To be frank, she really doesn't know Naruto that well (at least, not the same way that Sakura does), and she doesn't play a big role in his personal life either. It feels like her love for him spawned out of no where. Her love for Naruto actually reminds me of Sakura's love for Sasuke in some ways.
Sakura wanted to be acknowledged by someone, and one day decided that it should be Sasuke, the most popular boy in school. Similarly, Hinata wanted to be acknowledged by her clan, and one day she noticed Naruto and decided she wanted to be like him, the hard working underdog that never gives up. As sweet as that may seem to some, I still find it very superficial. They didn't fall in love with the person; they fell in love with the image. Yes, I'm going to argue that, because neither really went out of their way to get to know Sasuke or Naruto.
Sakura tried, but Sasuke was quick to cut her out of his life. Hinata, however, did not. She was inspired by Naruto, and all of her hard work came from that inspiration, but she never went out of her way to get close to him. This is reflected in her actions. Like, for instance, how she's always underestimating Naruto in battle. During the Tracking Itachi arc, Naruto gets punched into the pond and Hinata panics. Sakura, however, knows that Naruto can handle a punch or two, and tells Hinata to keep her eyes on the enemy - Naruto will be fine. And he was fine, just like Sakura said he would be, because she knows him well enough to understand that he can take a few punches and still get up afterwards.
Another example: While the rookies made the decision to stop chasing Sasuke, Hinata went right along with them and didn't even consider how that might affect Naruto. Likely because she
didn't know how it would affect him. Compare that to the way that Sakura reacted. Her actions were based off of Naruto's feelings. She knew right away how he would respond, and she wanted to do something about it. Hinata didn't do that because she simply didn't know.
That's the thing about Hinata that some people don't want to acknowledge. She's a side character. She has no significance to the actual plot, which has arguably been the biggest chapter in Naruto's life: saving Sasuke. She plays such a small role in his personal life, it would feel so odd for her to be paired up with him. Sakura, on the other hand, knows about all of this and more when it comes to Naruto.
She grew up around him, she made an effort to understand him, and she was the first female to
vocalize her acknowledgement of him. Hinata had acknowledged Naruto before Sakura, but to Naruto, it's the other way around. Why? Because Hinata didn't make an effort to be in his life, so that role goes to Sakura. She's one of his four most important people, and I'm not trying to say that Hinata isn't an important person to him, but it will always be a fact that Team Seven is like family to Naruto. Iruka, Kakashi, Sakura, and Sasuke... They were first. Not Hinata.
Anyway, my point is similar to yours. Sakura and Naruto have been together through thick and thin. They've grown to understand one another like no two characters I've seen before. That's why I enjoy their relationship so much. Their love feels real. It comes with laughter, heart ache, sadness, anger, happiness... All of the little bumps along the road that one should expect to deal with in an actual relationship.
