I've seen almost everything WA has made. Here is my personal ranking.
Rushmore
Royal Tenenbaums
Fantastic Mr. Fox
Life Aquatic
Darjeeling Limited
Grand Budapest
Moonrise Kingdom
Asteroid City
Bottle Rocket
Isle of Dogs
French Dispatch (This is the only WA film I just didn't like at all. Tried watching it three times and fell asleep every time)
For me, It's really about tiers. Rushmore, Royal Tenenbaums and Fantastic Mr. Fox are a cut above the rest to me. Those are three remarkable films. But I think my age (45) and when those films came out might cause me to over-rank them. Saw Bottle Rocket in the theater the summer after I graduated high school. I was a sophomore at UT in 98 when Rushmore came out and I remember seeing it at the Dobie. Probably watched it 100 times over the next 5 years when it came out on VHS. So those two films came out during my peak years of media/culture consumption. Then WA managed to somehow meet (and for some, exceed) expectations with Tenenbaums. Gene Hackman's character is an all-time favorite, and it's the best thing Ben Stiller has ever done. And Mr. Fox just blew my mind when it came out. I love it.
LA, DL, GBH, MR, and AC are pretty interchangeable depending on my mood. I love them all fairly equally, but just a tad bit less than the top 3. I realize I over-rank Darjeeling Limited. I don't know why I really love that film because it's got some problematic subject matter with "three spoiled white brothers bicker in India and generally act like jackasses". But still, I love the film. And I also realize I under-rank Grand Budapest Hotel. I think I need to re-watch that one.
Love Bottle Rocket but it being his first film, he hadn't fully-developed his style. But it was really quirky and funny and weird when it came out, and still has some of his best lines. It's in it's own category.
Then we've got Isle of Dogs and French Dispatch. I wanted to like Isle of Dogs. I really did. But I thought it was boring. And I just do not like French Dispatch at all. I tried watching it three times and fell asleep each time. It's the only stinker in the bunch.
I looked at a couple of other rankings on some websites and the funny thing is everyone's ALL OVER THE PLACE. There seems to be no consensus regarding where each film should rank, except that French Dispatch was always in the bottom three of every single ranking.
