Cinderella, Snow White, and Jasmine as well.

All the classics, and Mulan..

Aurora and Cinderella's personality.

I don't see why you would value Mulan's wardrobe over her numerous amazing qualities, such as her bravery, intelligence, and selflessness.

^ I can't not see this as an attack on me.

If we define intelligence as street smarts and problem-solving skills, I don't value this in characters at all, my most hated animated characters ever are Chel and Tulio and I guess this says a lot about how little I value this quality. Bravery is more valuable than street smarts to me but I can still dislike brave characters( e.g. Merida). Talking about Mulan's selflessness, I consider her selfless highly exaggerated. Also why not wrong to prefer Ariel's or Aurora's wardrobe/voice/looks over their personality but suddenly it's wrong to do the same Mulan? Aurora is selfless, Ariel is brave. AudreyFreak is right, Mulan is expected to get special treatment in this club.
Also in no of options I mentioned specific personality trait. The aspects I compared didn't include personality traits, I compared overall(!) personality of each DPs to her design, voice etc.
