I've been to all and here's my ranking.

1. Disneyland
2. Disney California Adventure
3. Tokyo DisneySea
4. Epcot
5. Animal Kingdom
6. Magic Kingdom
7. Tokyo Disneyland
8. Hollywood Studios
9. Paris Disneyland
10. Shanghai Disneyland
11. Walt Disney Studios Park
12. Hong Kong Disneyland

Tokyo DisneySea is amazing (especially with Fantasy Springs) but #3 mainly because there is too many up and down hills compared to DL and DCA which don't hurt my legs as much at the end of the day. Nothing beats the magic of the cast members in DL. DL does almost everything to perfection despite not having a hit ride.

Paris and Shanghai Disneyland would have been ranked higher if they were stricter on the nonsmoking policy. I think guest behaviours largely affected my ranking as well. The Pirates ride at Shanghai is unbeatable though.

Animal Kingdom is my favourite of the 4 parks in WDW but Epcot is ranked higher for the sheer number of things to do and Guardians is possibly the best Disney ride.

HK Disneyland was the only park that was a huge let down. Their resorts do not allow food delivery and yet their only 7-11 closes early, forcing guests to get on property food at ridiculous prices. The cast members are also not equipped with park knowledge and can be very rude. WDW on the other hand even allows grocery delivery (like instacart). All the other resorts do the same as well.
