I would say out of the unofficial princesses, Queen Kida from Atlantis: The Lost Empire is the strongest and most independent princess. She's the only one shown actually caring about the peasants of her kingdom, she has combat skills on the level of Mulan, healing powers like Rapunzel and can become a solid crystal to magically protect her kingdom in times of danger.

Out of the official 13 Disney Princesses, it's obviously Mulan. No doubt about it.
