IT sounds like OP chose BC or YC, and those are both fine choices. My instinct was to say something along the lines of, The best resort is whichever resort appeals to your family." Having been a forum member for long time, many people have a favorite resort, but different people have different favorites.
Personally, my favorite is the Contemporary. It doesn't have the elaborate theming of some of the other resorts, or the best dining options, but I love the convenience/efficiency, the view, the monorail running through it, and the water parade.
For theming, AKL is amazing. It is the only resort that is fully immersive. I feel like I am far from WDW when there.
That said, BC and YC are also places I often choose. It is great being able to walk to Epcot and HS. The pool's sand bottom is unique, and there are many dining options. If you will be doing some Table service dining, then you might which to have park hopper tickets, so you can dine in the World Showcase at night. Both hotels are also cheery.
Last though, well....many folks start out saying they will make 1 trip to WDW.... some stick to that, but others decide to return.
