Depending on your travel needs and preferences, why not split the difference and buy at both. It might mean moving mid stay sometimes, but sometimes it's nice to experince different resorts.
Truth is, buy where YOU want to stay (or think you will want to stay over the long term) . We bought 5 years ago, when SS was all that was selling. I told my guide I wanted BWV, so was going to wait until I could put a resale deal together. After a few months he called back with BWV points. IT WAS THE BEST THING I EVER DID! For the first few years, we would stay at BWV during F&W and OKW in Feb (which I was able to get at the 7 month window). And really liked OKW. But for the last couple years have just stayed at BWV. Everytime we go now, when we arrive at BWV, we really feel like we're "home"
