I think any hotel will do.
Mine and my mothers favourite is beach club (nice pool and sand beach, restaurants (beaches & cream, cape may even if ive heard its tot as good as before) boardwalk and location). My wife and mother in law loves grand floridian (best rooms, fireworks every night, lovely grounds and fantastic lobby. They are probably right. Its the most expensive resort.). We love them both so much so thats our two home resorts as dvc members.
My oldest daughters (17y) favourite is animal kingdom lodge, Kidani, which was our first dvc deluxe hotel we tried for two weeks during chistmas and new year. She likes it for the bread service and sanaa in general, the kidani pool and community hall… and it has a freakin savannah

we were in a savannah view studio close to the lobby. We saw zebras and giraffes from our balcony every day. Everyone in our family love this resort.
My 14 year old daughters favourite is boardwalk. Best community hall. I liked the pool, easy and beautiful walk to hollywood studios, my favourite gym and bar. We stayed there 1 week in a studio and 1 week in one bedroom. Big mistake. I recommend not to try 1 bedroom after trying hotel rooms. Its very hard to go back. Wife and I love 1 bedroom now (real kitchen, fridge, laundry, big soft king size bed and fantastic bathrooms) we try to add it to the end of our trip but start with studio to save some money/points.
(My youngest daughter, 6y now, favourite is bahama bay. Not a disney resort. Im sure she will get an favourite disney resort aswell

to make it harder for us to choose )
Thats the deluxe hotel we tried but its always fun to try new ones. Were going for two weeks in december (7 days polynesian, 2 days grand floridian new dvc room key pine and 6 days animal kingdom jambo 1 beedroom.)
I dont think you can choose wrongly. We loved every resort we stayed at. Its really hard to pick a favourite.
