We have stayed at all the WDW
DVC resorts now. On our last trip, we stayed at BCV, BWV, and SSR. In our most humble opinions, yes, the rooms are comparable to BCV, BWV, and VWL (but NOT OKW, obviously). HOWEVER -- it's the layout that really gives you that final impression. While the actual space seemed comparable to BWV in our 1BR, we immediately noticed the lack of closet space! Very shallow in the master BR-- and no entry closet at all. Also, in storage space. THe master bath had precious little (compared to BWV, which I thought had less than say, VWL, and certainly OKW). The bathroom sink counter was "cut-away", which left just a tiny ledge to perch things on my "side" (nearest the closet). We also thought the bathroom area "seemed" smaller because of all those DOORS and the positioning of things. At SSR, the toilet was in separate space behind its own door; at BWV, the toilet and shower and sink were all in one seemingly much larger, open space. I found the open area at BWV amusing -- like, what was I supposed to do there, dance? Personally, I liked having the toilet separate at SSR, but the 2 doors leading in/out of the shower/sink area were a nuisance. THe BWV bathroom always made me nervous... all that space as I noted before, plus, you're technically facing right towards the door to the living room, so if you aren't careful to lock those doors, and your kid decides to open it up while you're striking the toilet pose -- well, there ya are. Yikes.
Anyway -- SSR is probably comparable to most of the WDW DVC properties as best we can tell (BCV, BWV, VWL), but OKW stays in a catagory all its own.
