It also gets a bad rap because of its location. Lots of people want to be close to at least one of the parks. With Bay Lake, GF and the soon-to-be Poly, you're a boat or monorail ride away from the MK. Heck from Bay Lake you can walk! Boat ride away to Mk from Wilderness Lodge as well. And a boat or short walk away from Epcot and the Studios for Boardwalk & Beach Club guests. There's no "cool" way to get to Animal Kingdom from the AKV, but it's still close and has a pretty decent and dedicated bus line.
Meanwhile, SSR and OKW are boating and walking distance to Downtown Disney (and for OKW, that's a bit of a stretch, because while there is a walkway it's a bit of a trek especially if you're on the other side of the resort). For people who like feeling a little more secluded, it's great. For people who are shopaholics, awesome. Also great for people who want to do other things besides the parks from dawn till dusk, as you're close to many restaurants, DisneyQuest, Splitsville. It was great when Pleasure Island was still open, but since I'm now a dad it would have been a good long while before I imbibed at Adventurers' Club again anyway. You're close to the AMC multiplex, Raglan Road, Planet Hollywood, Cirque du Soleil...so there are things to do. And yet it's far enough away that it doesn't feel like you're in the middle of the madness.
But if you DO want to hit the parks from dawn till dusk, SSR seems like a looooooooong ride away. Especially with the multiple bus stops (I'd recommend having a car if you stay here and maybe only use the buses when you're going to the MK).
