Bought BWV because it is by far the best DVC resort of them all (just kidding... a little).
Actually, we own at BWV (since 1997) and AKV (since before it opened in 2007). Looked at OKW (then known as Disney Vacation Club) in the early 1990's. Thought it was a good idea, particularly that you could stay on site and get 1BRs or 2BRs (room space has always been important to us). However, we did not care much for its location, away from the parks, or that it was so spread out that you would often have long distances to a restaurant and the main pool. Reminded us of the Fort Wilderness trailers (latter to be converted to cabins) where we had stayed before and did not care much for because of the lack of hotel amenities and need to take a bus internally to get to anything (note that position has mellowed over the years and now we are fine with OKW, including because I have a daughter that owns there and thinks it is nirvana; for a while I kept wondering where we went wrong in raising her).
By the time BWV opened, our preferred hotel location had become the Epcot resorts (YC and BC) though we had also stayed at the MK resorts. Thus, BWV was an easy purchase including because it was the only near park resort that existed at the time, allowed walking to Epcot and thus to all its restaurants, and was built as part of a combined hotel/DVC resort where the main pool was on the DVC side and you had easy access to everything in the resort and the boardwalk.
Bought AKV before it even opened. We had stayed there and particularly liked the savannas with animal viewing and theming, but actually most important in the decision was Boma (which we consider one of the best buffet restaurants), Jiko (an excellent table service with a never ending wine list) and Mara (a counter service convenience we did not have at BWV). Despite that we now stay mainly at Kidani, which has only Sanaa (also one of our favorites) but we choose it because of the better and larger 1BRs and 2BRs and more convenient parking, and Jiko has more or less become a thing of the past because its prices have become prohibitively high for us.
Despite owning at BWV and liking it, I have ceased giving high recommendations to others to purchase there. It is mainly an issue of time. It has a 2042 end date and that seems to me to be too soon for any new purchaser under 50.
