Pakey did a great job of breaking down the sections.
I have stayed in all sections at SSR, our favorites were the Grandstand since it was first on the bus route and we enjoyed the pool there and being close to the High Rock Springs main pool, the Paddock because we loved walking across the pretty bridge over to the main area (a new main pool will really make this section great) and Congress Park.
Congress Park might be my most favorite since it has a great quiet pool with a gorgeous view of DTD, esp at night. My husband and I would enjoy a glass of wine in the rockers they have right off that pool by the rivers edge, looking at the lights of DTD while our kids swam. Best quiet pool in WDW! And being so close to DTD is great for us. We do not rent a car and we enjoy dining at other resorts so being able to easily walk over to DTD and get on a resort bus there was wonderful and time saving for our dining plans.
I'll add that the Carousel is nice. Its the furthest out but its so quiet back there. And if you do have a car, its nice to be very close to the main entrance. And with the new pool going into the Paddock, that will make this section more desireable. It was around a 10 minute walk to the main area at a leisurely pace from the Carousel.
I also don't care for the Springs, our room was right above the road where the busses stopped and it made sitting on our balcony less than tranquil. We are also quiet pool people so being in a section that has one is nice for us. It was convenient but not high on our list to ever return to.
SSR is wonderful, one of my favorite Disney resorts, I hope you enjoy it too!
