Beach Club Villas - 1 Bedroom. This is a brand new resort so that is always nice. As far as location between the BC and BW you are basically a 5 minute walk between either one, so that doesn't make a difference, love the location of both, there is a 5 minute walk to Epcot from the Beach Club and about a 20 minute walk or boat ride to MGM.
The Beach Club has Stormalong Bay which is the best and the biggest pool on WDW property. The Beach Club in my opinion is a little more quiet then the Boardwalk, but still within a 5 minute walk to the Boardwalk if you want to walk over there at night. If you don't want to go over there you can just sit on the beach in the evening and look accross the lake at the lights - its breathtaking. Other option would be to walk over to illuminations in the evening and walk the 5 minute walk back.
As you can tell, Beach Club, and now the Beach Club Villlas is my favorite resort.
