It's really subjective and there are factors involved. What is the make up of your party? How many people/kids/adults? Do plan on just using the room for sleeping or are you planning on spending some time at the resort? You said you will have your own car, do you plan on driving to the parks or using Disney transportation? Can you afford to spend more or are you on a tight budget?
If you don't have more than say 2 adults and 2 littles, the AS would be o.k. The rooms are smaller but two littles would fit in one bed. The pools tend to be fun for the littles because of the theming. The value resorts can be noisier than the other resorts just because they do tend to stay booked up. They have stepped up their game though and the rooms, while smaller than the moderates, have been upgraded and are on par with the moderates.
I would not stay at AoA unless you need a suite. In my opinion it's just not worth the money and I'm not a huge fan of the sky liner so that is actually a reason I wouldn't stay there. Again, if you plan on driving it comes out of the equation any way.
I love CSR, actually have a stay there coming up in December on my AP discount. I am not staying in the Tower. I toyed with it but frankly, since it's the last bus stop to pick up I know I would end up walking over to the first bus stop and actually enjoy the other areas. I'm going with a preferred room, which I don't normally book but with the discount I figured why not, that way I know I'll either be in Casitas or Cabanas. For adults its a great resort. Kids enjoy the pool since it has a slide but that would only be if you have bigger kids. I would only choose it if you plan on spending some time at the resort though, I don't think it's worth the extra money if you are going to be in the parks most of the time. I tend to stay there because I love me a hot tub, which the values don't have and I love Three Bridges and just the over all atmosphere of the resort, but I am an adult with no kids and not on a budget.
