We stayed at POFQ last year and CSR this year. Honestly, we loved both.
FQ only has one bus stop so that's nice not to have to stop at several stops before heading to the park. It's also a lot smaller property than CSR, so not much walking around to get somewhere. When we stayed, we stayed in the VERY back corner...the furthest room from the bus stop/lobby. Even then, it only took 10-12 minutes to walk there at a leisurely pace. The QS was pretty good (it may have changed since we've been) and the pool pretty cool, but typically crowded as it is the only pool on that site. Overall, it's cute fun resort and would definitely stay again.
CSR was beautiful. Overlooking the lagoon to the other areas of the resort was one of our favorite things to do. With that said, it is a very LARGE resort property, so, depending on where you stay, it could be a long walk to your destination. Thankfully, they have bus stops outside of each area, so you don't have to walk too far. We stayed in Casitas 3, and it seemed as though it was the best place to stay. It was only a 3-5 minutes walk to the bus stop (which is the first stop on property, so you are essentially guaranteed a spot on the bus), a 5 minute walk to the lobby, and an 8-10 minute walk to the pool. There are several food options here and we enjoyed everything we ate there (which admittedly wasn't all that much). The pool was also very large and, at least while we were there, was never overly crowded. The slide was fun too. There are some other small pools in each section as well. Overall, it's a beautiful, relaxing resort and we would also stay here again.
I really couldn't choose one over the other, as both are great moderates. A plus at FQ that you dont have at CSR are the boats to Springs...that was nice to have.
*Side Note: CSR is under construction, I'm not sure how far along it will be by your trip next year, but as for this year, you could barely tell and it didn't ruin anything for us.
