In the past 6 months I've made my first stay at each of these resorts. I liked both of them.
I had a 2BR BW view at BWV. It was nice to sit on balcony and people watch, watch the fireworks, etc. Being able to walk to MGM and Epcot was nice also.
Had a 2 BR at OKW, also. OKW has a more laid back feel to it. It was very relaxing. Unit was huge! We were 6 adults and never felt crowded. Parking was great there, too. Although I love the excitement of the parks, it was nice to go back to the unit get away from that at times.
