Personally, I'd choose CSR over CBR. I've stayed at both but just felt that CSR was nicer. The pools were great and even though our room was in Ranchos, I didn't mind the walk to El Centro. The scenery was so beautiful that it made the walk seem faster and DD (2 at the time) loved to stop and look down into Lago Dorado for turtles.
All of that said, POFQ still remains by #1 Mod. Maybe it's because it's where DD and I stayed on her first trip, but the resort just summons up so many wonderful memories. It's beautiful and quaint, everything is a mere 5 minute or less walk, but it's amenities double when you factor in that you are entitled to use everything at POR as well. We used to walk or boat over POR at night for either dinner or a snack but always so DD could see the "horsies!"
