I know this doesn't directly answer your question, but my first reaction on reading the post was that there are so many wonderful and fun places to eat at WDW, I'd just encourage you to eat other places in addition to the Pepper Market (right name?) during your stay. This may not be entirely possible if you're on a tight budget, but going to WDW and eating at the same place over and over again would just seem terribly frustrating.
Having said that, I've stayed both places, and I love CSR - it's just beautiful at sunrise and sunset, as well as after dark. I recommend the Cabanas, because they're only two story buildings, where the other sections are three and four stories.
Also, despite what you sometimes read, it's not farther from the theme parks than the other moderates, and it's closer to AK than any others. (Even though CBR is right behind Epcot, travel time to the front gate is about the same.) CSR *is* farther from Downtown Disney, if that's an issue.
I'm sure the CBR fans will have their input on this one as well.
