I go to WDW several times a year and normally stay at moderates (not a fan of the values). However, CBR is my least favorite moderate. Even so, I'd still choose it over Pop (especially since the price is similar). At the moderates you will have a bigger room, coffee pot in room, hot tub, pool slide, nice covered bus stops with benches, TS restaurant, and nicer theming (white sand beaches with hammocks), plus the bus stops coming out of the parks is normally closer (Pop has a tendency to be the very last bus stop it seems).
Pop does have the better food court though. It will also feel alot busier and louder. I've stayed there several times, but it's been awhile. If I ever stay there again, I'd rent a car.
off topic: you said Pop and CBR were about the same price. I'd check to see if you could get POFQ or CSR for close to the same price. They are my two favorite mods and both have queen size beds (whereas CBR is the only mod to still have full size beds), plus at POFQ you'd have the boat to DTD. CSR has the nicest main pool and the longest pool slide of the moderates and has the biggest hot tub on property. You can refill your mug and order food right there at the main pool, without going over to the main building and they have the best bus service on property.
