I had the same decision to make, and ultimately decided on PO-FQ. We love the theming, the compactness of the resort and the fact that we have access to all of the amenities of the sister resort, as well!
CSR just seemed too spread out, and when we visited, it just didn't seem to have that Disney feel.
I did see that you asked about kids. Did that mean you wanted them around, or didn't?
PO-FQ will probably have more kids, just because it is easier to get around---that is part of why we choose it, too! CSR is likely to have less due to the fact that it is also a convention resort.
So perhaps that will be the deciding factor for you.
