Which food court a person prefers is really a matter of opinion. I have been to both of them and they are both nice. ASMO is newer so some people like it better. The nice thing is that if you stay at either one of them you can walk to both of them and try both out for yourself. The first time we stayed at ASMO we were in the Mighty Ducks building which was closer to the ASMusic food court than ASMO'S. Both basically have the same type of food.
I think the Movies food court is the better of the three All Stars
resorts. Reason being, it is newer and seemed to have a better
selection. I think the lay out of the food court at the Movies is
much better than the other two.
