Of your choices, I'd say 1900 PF, based on experience. However, I have heard fantastic things about the Boma breakfast.
As far as PF goes, it is our family's favorite...that is including CRT. The princesses are somewhat Foodies, (meaning they know food, they know quality, and can judge a good meal), and they call this the best breakfast, by far, on property. I don't have the heart to tell them that statement is meaningless until we have eaten at all establishments. Anyway, for not only quality but also variety I highly recommend 1900 Park Fare breakfast!
We are breaking tradition in August and skipping this breakfast, in order to try the dinner (Cinderella's Gala Feast). I hope we don't regret this decision.
Bon Appetite!!!
