Maybe. Or Rapunzel, I think both could annoy her. I think she'd be pretty neutral about Aurora, at least not really be bothered by her.

she'd think Aurora is just passive, doing what others tell her

Too passive, opinion-less and emotionless, not really the way an actual human would act

oh, definitely

I can't see they be so good friends, their personalities are too different and I think Mulan wouldn't like to be around Aurora since she's so "perfect".

Mulan seems to be tolerant of other flaws, considering that she befriended Yao and Ling. I imagine Mulan being very judgmental of what Merida did to Elinor( because Elinor is Merida's mom, while Yao and Ling bullied a stranger so this might be more forigivable for Mulan) but definetely getting along with the rest.

^^

also, Mulan tried her best to be perfect because she wanted to fit in/please her family. why would she judge someone else just for naturally being good at stuff she isn't?

Yes. For hundredth time, Mulan is an easy going chick, she doesn't have anything against more feminine or bubblier personalities.

Seeing older polls where this mentality around Mulan was still prevalent is interesting though.
