It depends on room type and party size.
OKW is a fun "bang for the buck" with large villas for relatively low points. And a nice tropical feel. (A legendary former poster and OKW owner joked during an early BWV stay that BWV 1BR was great because he could reach into the fridge, from the balcony for a drink)
OKW studios have 2 queen beds which can be an advantage for 2 beds, or a problem if you like a couch to sit on.
Most OKW buildings do not have elevators, so you may need to walk up stairs to a 3rd floor.
SSR has a room layout very similiar to BWV, and has better Disney Springs proximity, 2 feature pools and 2 eating areas.
It's certainly worthwhile trying all resorts at some time!
