Interesting question since we just did about a week stay at both over the past several months in the 2BR villas.
Our latest was to SSR (a few weeks ago) and had a great location in Congress Park. They put us closest to the boat dock at DS. That actually served us very well as the boats could take us to POR/POFQ and SSR near The Turf Club (which we did use rather than walking from it). SSR was very clean and comfortable and exceeded my expectations. It had enormous televisions in both bedrooms and the LR. Service at SSR was impeccable. I'll post a review shortly.
OKW is my favorite DVC resort at WDW. We managed to get another canal view 2 BR villa which, to us, makes the experience. This past spring, we were on the first floor in building 45 (the time before we were 3rd floor in building 46). We got to do the "OKW Wave" exercise each time a boat passed by our deck. It was comical and enjoyable. I will post a review I did from OKW and share our latest experience shortly.
