..Sakura of course..Well this is just my opinion but Sakura and Naruto a better history together.They are on the same team. Naruto said he likes Sakura.Kushina even stated she wanted Naruto to be with a girl like his mother.Kushina and Sakura are similar..So..Yeah..I mean I know Hinata likes Naruto too and I have nothing against her but I don't really see them together..Look at Naruto Shippuden Road to Ninja..
Nothing against Sakua but Sakura will have to come out of Sasuke shell to be with Naruto. If Sakura dont have true feelings for Naruto, Naruto will reject her again (as far as we know Sakura still thinks about Sasuke as her love interest) and that not possible while Sasuke is alive. Also as for Road to Ninja the genjutsu shows Naruto what he truly wants in his heart, which wld mean Naruto wants Sasuke to pay attention to Sakura while he wants Hinata to become much more bold and forward towards him. Still the movie is not canon i think.
Also we actually dont know what will happen for example who expected Ron to end up with Harmonie in Harry Potter?
As for similarities......

1. Hot Temper: Well the only similarity that Sakura possesses, but note the fact that at the age when Sakura was crying about for being teased for her large forehead (Ino came to rescue remember?)
