I like the theming of AKV, but I don't like that it is so far away from the parks. I bought BWV by resale, because I value the closeness to EPCOT and the studios. There are good and bad points at all of the resorts.
BWV does not have a counter service eatery, long hallways, a little older and from posts I've read, some of the rooms are showing wear and tear (the room we had in March was beautiful though), maintenance fees are the highest of the WDW resorts. The location is what attracted me. It is also smaller than OKW, SSR and AKV (in the future) and I'd be disappointed if I was not able to stay there.
Lots of people on the boards will have good advice for you. In then end you should decide what's really important to you, and make your decision based on that.
