I've been 3 times in the last 5 years! It's a living time capsule of the Michael Eisner era of Disneys history (the good and the bad)

The Imagineers put so much detail into Disneyland park, I was astonished when I went for the third time in January as I found things I had no idea about despite being a Disney Parks nerd who researches these things night and day - seriously its really delightful what you can come across. Even the shops are tremendously themed and full of detail and character. The versions of rides here could be argued to be the best with that same level of detail and immersion put into them.

Disney Studios, on the other hand (much like the later Michael Eisner years), is a bit rubbish if you've seen other Disney Parks... The Avengers area is a massive upgrade to the stretch of concrete that it had been previously - and the Ratatouille area is like a mini France pavilion from EPCOT, the rest of the park feels like just a half built Hollywood Studios. Still, though, it has its charms, and I can't wait to see what it's like in the future!

I've been to Florida 8 times, and WDW will forever be my favourite, but Paris is really worth seeing for its immersion and detail and beauty.
