We've stayed at CSR a number of times and love it there. The pool is terrific, slide is fun (even for us adults!), and we've always had good food at the Pepper Market, although we haven't tried any of the TS places. I've heard Maya Grill is good, though.
However, we were up for a change of scenery so we're trying POFQ on our upcoming trip in just a few days.

My husband and I stayed there for an anniversary trip without our kids and we liked it, but it was 9 years ago. I'm interested to see what the kids think about it - I am pretty sure they'll be disappointed by the pool but it'll do for quick afternoon swims to cool off. I plan for us to spend at least part of our rest day over at POR to check out their pool and food court, so if I think of it I'll update in a couple of weeks with my kids' impressions of POFQ and POR.
One thing I've always liked about CSR is the totally immersive theming, and how I really feel like we're in the desert southwest. Being Floridians, we have a lot of the Caribbean-type architecture in our area, as well as the old Florida/Southern style. Lots of oak and magnolia trees, and POR just seems like it would feel like being at home. While the Casitas at CSR are considered "preferred" due to their proximity to the convention area on that side of the main building and adjacent to Casitas 1, we've always preferred the Cabanas area. It's not too far from the main building, and the bridge goes right across to the pool area. The Ranchos building that is next to the quiet pool is a good location, too. It's only about a 12-minute walk to the main building (walking with children), and 3 minutes to the main pool. If you can spring for the Business Class rooms in Cabanas 9B, they're very close to the main building, and are a club-level-light with drinks and snacks available.
Good luck with whatever you choose!
