You don't provide us much in the way of criteria, so it's difficult to say. So, let me answer by assumption.
Assuming you don't care about the bathroom situation
SSR, at least the newly renovated rooms in Congress Park. The access to Disney Springs is unbeatable, and with all the new lounges and restaurants there, it's a mecca for adults looking for better standard fare than in the parks or most resorts. Further, you have boat access to Port Orleans, a golf course, a huge fitness room, a spa, and expansive tennis courts. The bus situation there is fine, though there are a few stops within the resort at the various areas within SSR.
Assuming you prefer more bathrooms
You don't mention the adult situation (couples, all single friends, e.g.), but if I had the points (or $$), I'd opt for a resort with an extra bathroom, and Kidani is one of those resorts. As mentioned, the 2BRs have three bathrooms which could be a godsend. The buses there are also generally as good as anywhere else, but that is your only option outside of paying someone to haul you around. On the other hand, the resort is gorgeous, the pool area very nice, and there's a solid pool bar attached to it. Sanaa is one of the better restaurants on property, as well.
Assuming you want space
OKW has more square footage, thus more elbow room. It also has a very relaxed vibe. Again, you're limited mostly to buses, and in our experience, they seem to be a little fewer in number, but that may just be us.
