Jasmine: confrontational and takes matters into her own hands
Cinderella: non-confrontational and leaves her fate up to others

Or Snowy.

Aurora: Passive and dreamy
Jasmine: Assertive and realisitc

I don't really think Jasmine is realistic at all. PERSONALLY I think Jasmine and Aurora are very alike, they're both sheltered and innocent, not always bright, but for their life is pretty noble. Cinderella and Jasmine is where I think the roads split. Cinderella stays put, while both a little sassy, Jasmine is upfront Cindy likes to lie down. Jasmine goes out of her prison to find freedom Cinderella seems to favor sitting to dream of a better thing.

and I agree, I don't find Jas particularly realistic. she is also a romantic and doesn't handle change well when it doesn't match up to her own ideals. I also see similarities between Jas and Aurora, but I still choose her.

Jasmine: Outspoken, bold, reckless, stubborn, authoritative, wears the pants with Aladdin.
Aurora: Shy, timid, responsible, compliant, unassuming, lets Phillip take the lead.

Cinderella is more assertive and shows impatience occasionally, so that's why I didn't pick her. and she doesn't leave her fate to others (though she has little choice)- she's the one who decided she'd go to the ball after all and finds little ways to defy the Tremaines. Snow is easily the most like Jasmine- very outspoken about how they feel and not afraid to push others around.

Or Cinderella.
