We just returned from WDW, and we did both princess breakfasts. At Epcot, we saw Snow White, Belle, Jasmine, Mulan, and Sleeping Beauty. At Cinderella's Castle, we saw Snow White, Mary Poppins, Sleeping Beauty, Belle, and Cinderella (who was actually Belle from the day before). It seems like they have the same number of characters, just a little different depending on your preferences.
