Such a fun topic! So many choices and few wrong answers.
To quote Queen "I want it all and I want it now."
That said:
France. The fountains at night, Impressions, Belle and Aurora, oh...and FOOD!!!! At this point, the wine cellar would need some serious restocking. Plus, some ride's about to open there, IIRC.
After France, so much goodness remains.
Germany: Beer Hall, food, beer, music, beer, chocolates, beer...did I mention beer?
Mexico: The wife would never leave. Margaritas, tequila, River of Time, margaritas, doing shots with Donald...and, of course, great food.
Japan: Love the atmosphere, love the food and performances.
UK: Beer, again. Pub food, and it almost feels like a small town.
Canada: Love the gardens and waterfall, and having a steakhouse is a good thing. Plus, rock and roll!
Morocco: Fun atmosphere, good food. Get me Jasmine in her Old School outfit, I'm sold.
Norway: Like the ride, both old and new, never had the food there, but love the treats and the atmosphere. Fully staffed? It'll be Princess Paradise!
Italy: Okay, like the food, but there's just not much there, there.
America: I like it, it's home, but the familiarity makes this kinda "eh". Plus side: Turkey Legs! Funnel cakes! Plus, I love BBQ, though still haven't tried Regal Eagle.
China: Gift shop is fun, I've never tried the sit-down restaurant, good entertainment, but the quick-service dining is blah.
So, it's France FTW for me, but there are so many other great choices, you really can't go wrong.
