Answers on this will vary wildly.
Lots of people hate CBR because of their buses, but you'll hear the same complaint about POR. POR is smaller and people love that, but CBR is also right next to Riveria and that gives it a boost.
It is going to come down to your preferences.
CBR: has biggest rooms of any moderate, the Skyliner (access to EPCOT area resorts, plus EPCOT and HS themselves), a zero entry pool with 2 waterslides, a large splash pad for young kids and older young kids, average dining options, lots of resort recreation (beaches, playground, bikes), pirate themed rooms, and good theming.
POR: Good theming, average sized rooms, has access to POFQ so you get to use both pools, recreation activities similar to that of CBR, Disney Springs boat, good theming, royal themed rooms, okay dining, have to take a bus or rideshare to get anywhere, not close to any resorts except POFQ.
Both have beautiful grounds, and if you consider POFQ and POR two resorts combined in terms of enjoying all the amenities, not that big of a size difference between CBR.
