I cannot comment as to the suites but I have stayed at each of the 3 resorts.
If I had to pick, it would be close between ASMu and CSR. ASMu is my favorite value. Super CMs (I stay there at least once a year), seems a little quieter than the other values. Love the theming.
CSR is a beautiful resort and I enjoyed the freshness of Pepper Market. I do not know which section has the suites, but some of the buildings are a long haul from the food court. Terrific pools and the Maya Grill is very, very good TS.
AoA has INCREDIBLE theming. But it had too many negatives for me. There seemed to be more "room noise" at this resort than AS--and I am a heavy sleeper. Very aware of babies crying in rooms and doors opening and closing all around.
The REAL negative is the food court. It has a terrible layout and it is just BEDLAM. The queuing lines are not nearly as long as they need to be. Service was sluggish and I can't tell you why. It seemed a bit understaffed, but not terribly so. It took 10-15 minutes (one time 20 min) to get through the lines and get food, then stand in line again to pay. By the time you are seated, the food is tepid. Then you have to get silverware, drinks, find a table, etc. The noise level is HORRENDOUS even at non-peak times. And the traffic flow design (WHAT traffic flow design??) is very poor. There is no real flow pattern.
Seating is ample, which is nice. You get real plates and silverware which is good news/bad news. I found that I bristled at having to so bus my own table. You have to try to get the trash and remnants into a trash receptacle with a too small door that is spring loaded to close. Then you sort of recycling and the dishes in one bin and flatware in another. It reminded me WAY too much of bussing tables in a restaurant.
Food quality was OK but not remarkably better than AS, which is what I had hoped for... The food "looks" better than it tastes. Naan bread is VERY good and I really enjoyed the build your own fruit bowls and yogurt/granola bowls for breakfast.
