Though I think that the villas are a bit smaller at SSR, it's nice being onsite and having either free theme park parking and/or Disney transportation as an option. Nice resort theming, lots of activities, good pools. The resort's location across the lagoon from Downtown Disney and is the most centrally located of the DVCs if you're doing something else in Orlando, like Universal or SeaWorld or just some outlet shopping, other than Disney during your stay. The one downside of a DVC exchange is the requirement to pay Disney's bizarre resort fee, which I believe is $95. But, if you haven't stayed at a DVC having the opportunity to try one out might be worth it. I'd further suggest that you do some research on what area of the large Saratoga Springs Resort that you'd like to be in and make a request before you go.
