There is so much to consider when choosing a resort to stay at...theming, location, vacation style, size and make up of party, time of year etc.
I have stayed at all level of resorts, and the only deluxes I have NOT stayed at are Poly and GF. There is something to love about each one!
To the OP... who is in your party? What time of year are you going? What are your favorite parks? Do you plan on doing parks most of the time or will you spend a lot of time at the resort? Your answers to these questions will help you better narrow down where you will be happy staying.
My personal favorites are: Boardwalk because of location, atmosphere and food choices; Saratoga springs because it is not near the parks and very relaxing yet it is close to DTD and has great pools; wilderness Lodge because of the theming and calm , relaxing atmosphere.
