Here are the bad things about Sakura:
Being mean to everyone for no reason, she could insult anyone, but anyone just call her name she attacks. Sakura judge someone by their appearance and is being about it like when Lee blew air kisses. Sakura broke her friendship with Ino and never ammended that just because Sakura got a crush on Sasuke. Sakura only thought of Sasuke, she never thought of anyone else even though guys asked her out to be her girlfriend.
Hinata she was really shy and had no confindent, she didn't have the courage to talk to Naruto and she faint if Naruto sneeks up on her. Hinata was shown stalking only once and that is mostly because Hinata didn't have the courage to talk to Naruto. As far as we know no one asked Hinata out, so she never rejected anyone.
I may have left something out since I may have forgotten, but those are the ones I remembered.
I say Sakura was way worse, she even broke her friendship and never fixed it with Ino.
