If you can afford it, I'd say go for it. We've stayed at the All Stars and Pop Century as well as POR and CB, and I think that there is a big difference. That being said, we are going back to Pop Century so that we can afford to stay longer (it really comes down to your budget)
I would vote for CBR as far as moderates go. I love the landscaping, and you can see the fireworks from both Disney Studios and Epcot at night. The downside is the size of the resort. If you get in the wrong room, you will have quite a walk to get to the shops and the food court and the busses have to make several stops while dropping guests off around the resort (if you have a car then this shouldn't be a problem).
I really don't think that you can go wrong with any moderate, they're all great, so if you can afford it, I'd say go for it!
