I've only been to POR, POR (when it was Dixie Landings), and CSR. Based on the buses at POR, I will never stay there without a car again. If I didn't have a car, I would demand a room as close to POFQ as possible so I can use their buses instead without a huge walk. CSR in my opinion is the best moderate. It has luxuries of a deluxe at a moderate price. However, the downside of that is there is less Disney theming. It has one of the best pools on property and it is never crowded because convention goers do not go there. The buses are one of the best on property. You are never too far from the main building. Just hop on the first bus you see and get dropped off at the lobby.
I do like the looks of CBR and will stay there eventually.
