Boardwalk or AKL are our favorites, AKL (at least kidani, not sure about jambo) also gets you a third bathroom in a 2 bedroom villa, which nets you a 2nd bathroom in a one bedroom villa. AKL is also super relaxing and has some adventurous food choices.
Boardwalk has a lot of cool stuff at the resort and walking distance to epcot and in theory Hollywood Studios (i'd rather take the boat). You're also within boating/walking distance of restaurants at Swan and Dolphin and Beach/Yacht
SSR is a close second with easy access to three different areas of Disney Springs via walking path behind Congress Park (Marketplace side), boat behind the Carriage House/Grandstands (center) section or bus access (regular resort loop closer to Cirque/House of Blues side.
