The set dressing of the DL and WDW versions is vastly different. Particularly the interior scenes following the first drop.
These scenes at DL's feel more swampy and compact/interconnected with less separation. The walls are generally obscured with scenery and mostly painted dark colors so it feels more like a darker densely forested swamp environment. Even the foliage used to fill out the ceiling looks very different, colorful hanging ferns (or perhaps it's supposed to be Spanish moss).
WDW's scenery feels more like a river carving its way along the edges of a forest. The walls now painted with brightly lit colorful murals of distant farmland, rolling hills, trees and sky. The scenes themselves are just as densely detailed, but also larger and better spread out and segmented from one another. Rockwork is more detailed and hilly, redder looking dirt and clay layers. Even the ceiling foliage is very different, using tree branches adorned with leaves instead of the hanging moss/ferns from DL. Some of the same differences are present in the riverboat finale scene as well. By and large, a significant chunk of the scenery at WDW is much better and more detailed IMO. This is not so much due to the different environment it goes through (though I do prefer that too), the scenery simply received more attention and detail than the DL version.
Tokyo's by comparison seems more similar to the setting of Cali's, again like it's deep inside a swampy forest. Same sort of hanging mossy/ferny foliage as DL as well, and largely obscured walls that lack the aforementioned murals of WDW's. However much like WDW, greater detail was put into the environmental scenery than Disneyland (mostly that is, I don't like the design of the Laughing Place caverns as much as DL and WDW, or the removal of the water wheel mill and shaft at the beginning).
Animatronics wise I believe Disneyland has the most figures by a small margin, Google lists it as 68 figures (which is roughly accurate from my count, though a couple of these are smaller simpler figures). It reuses the America Sings AAs, and a handful of characters didn't make it into WDW and Tokyo. Though it should be noted that the ones used for the main "Brer" trio from the movies have significantly better designs at WDW and Tokyo and several contain superior motion over their DL counterparts (especially the hopping Rabbit figure which isn't in DL). WDW and Tokyo also still utilize an enormous quantity on their own merits. At least 55 with a good range of motion from my count, and another handful of simpler figures I didn't even count. Greater by far than anything Disney has built over the past 20 years.
By any chance do you know which characters are exclusive to Anaheim? I’ve been on both and can’t think of any. I assume leftovers from America Signs that don’t quite fit in like the cats and dog? I’m more familiar with the Anaheim version so the specific AA’s don’t stand out as much as the scenery, which you provided a great breakdown on.
