Coronado is definitely the best of all the moderates. Since it has the convention center attached i think the kicked it up half a notch. Try to stay in the Casitas buildings, they are the closest to the main building with the restaurants. Also, there is a bus that runs between it and the Boardwalk most of the time which is a good alternate to get to Epcot, plus the Boardwalk has turned into a decent destination on its own.
