I'm going to be NO help. We did all three last year. CM - great farewell breakfast. Iconic, classic Disney. Food - so, so. (I actually cried when I told Mickey goodbye there.) Experience!
Ohana - you get to sit down! They'll refill plates, so no up and down. Stitch was cute, but in a hurry. In fact, they all seemed to be. Good food. Choose this one if you want to A. sit, and B. see Lilo and Stitch. Otherwise, the other two trump it. Really good juice!
Tusker House - Probably my fav. after CRT breakfast. Great food and variety, cool atmosphere. Characters were not in a hurry, even with all the tour groups interrupting "our time". Thank goodness for handlers! They have great juice here, too. AWSOME to get 8am ADR's here for 9am opening, head straight to safari.
