Somebody's a little touchy.
Sakura has grown from a little pink haired annoying little bitch to a big pink haired annoying bitch...that was a little harsh. (By the way that part was not serious so don't go hulk on me.)
Eh Sakura trained how to heal people and punch hard with Tsunade... not really sure how that makes her the strongest Kunoichi in Konoha.
It looks to me you have some kind of grudge towards Hinata, how do you have a grudge with someone who isn't even real? I have no idea.
Just because she was on most missions with Naruto doesn't mean she is the most important character, she never did anything in the first part of the manga, the first time she did anything important was with Sasori.
The reasons Sakura lasted so long against one of the Akatsuki members are.....
1. She had Chiyo who was an experienced puppet master ninja who new Sasori's tactics and was
his grandmother to advise her.
2. It was Sasori, not the leader of Akatsuki.
3.She had an antidote to Sasor's poison.
Reason Hinata didn't last long is........
1. It was the
leader of the Akatsuki... a "god" he calls himself, this guy killed Jiraiya and almost defeated sage Naruto, dude its no wonder she didn't last long.
I am positive that if Sakura jumped out to protect Naruto she would have lasted just as long......
How can you say Hinata hasn't developed as a person? Are you insane?
