For a 1 or 2 BR, I think I'd be happy to stay in CCV or BRV. There just isn't a huge difference. Jambo vs. Kidani is another story because, it can be a pretty LONG walk from the far end of Kidani all the way over to Jambo. You're not popping over to the QS at Jambo if you're staying at Kidani. At BRV or CCV, you can easily pop down to Roaring Fork or Geyser Point and be back at your room to eat your food if you want to.
Now, if you're thinking about buying a contract, CCV has the addition of the cabins and GVs that BRV doesn't have, and you have the far longer expiration date, and slightly lower dues. That's why I would personally never buy BRV over CCV.
