I really like all of them and take turns on BWV and OKW. BWV gives me quick access to BW and Epcot while OKW gives me a ton of room and makes me "feel" like I'm on vacation.
I voted for VWL, but may have considered VB if it had been listed. The reason for VB is that there are several WDW resorts that I like, and wouldn't mind paying cash for (AKL, Poly, WL, YC).
We have points at the BWV and the VWL, but the edge would go to the BW for us. We love them all, but I have a little bit of an addiction to the carrot cake at the bakery.
We bought where we enjoying staying the most and that is Boardwalk. I like the option to try others and we've really enjoyed our stays at OKW and BCV, but if we could only stay at our home resort I'd be happy.
We bought twice at OKW because it is, hands down, our favorite. We love the relaxed feeling we get there and we love the look and layout. We don't prefer the hotel type DVC's
We bought at OKW...still love OKW and if we get to add on again we will add on more pts at OKW....love that we have the option to stay at all the DVC's of course and we do go back and forth between them, but if they ever changed the rule to "you can only stay at your home resort" , in no way would we be devestasted
