Those loops are pretty equivalent. They are about halfway between the boat dock for the Magic Kingdom and the bus loops for everywhere else. They aren't far from the Meadows where the swimming pool and trading post are. I think sites there may be larger than nearer the boat dock.
I feel that loops are generally equivalent unless you have something specific you want. Most of them have one or two problem sites, but Disney is good at fixing problems unless they are completely booked.
Disney internal transportation is good, may be slow sometimes, except when the parks close each night.
