#1 it is the original Haunted Mansion.
#2 The stretching room actually stretches in California and is a very unique feature that made this attraction possible.
#3 New Orleans is the perfect setting for a haunted house and the exterior of this one has a traditional look.
#4 Many upgrades over the years debuted in California first. The floating Madame Leota head in the crystal ball for example. While some new effects have reverted back they first appeared here.
#5 The Nightmare Before Christmas overlay. Disneyland Entertainment did a fantastic job when they created this and it's the only one where basically you get two different attractions in one.
#6 Finally, the maintenance in California is the best thanks to the twice annual shut down to add and remove the overlay.
Between regular Haunted Mansion and Phantom Manor it is a really tough call. Phantom Manor is a spectacular attraction, but I think of it as a separate attraction rather than another version of Haunted Mansion due to the numerous differences in story and scenes (although the core of the mansion scenes are present in some form). Disneyland's Haunted Mansion is outstanding as well, one of the best dark rides in the industry and one of the few rides I can't miss on a Disneyland visit despite having an Annual Pass. I think I'll just call this one a tie.
If they just kept on top of the maintenance it would be perfect.
Never been to Tokyo so can't comment on theirs but the theming looks superb.
Even the name.. 'Phantom Manor' is much better than Haunted Mansion!
I voted for FL, but because I do not like the DLP version.
I don't like the overly and want there to be a permanent Nightmare ride and HalloweenTown area in DCA.
I'd love to be able to experience the classic Haunted Mansion in Disneyland at Halloween.
