Big Thunder Mountain Railroad has been eliminated and voted out! Big Thunder is an absolute classic and one of the most iconic rides in Disney parks worldwide. I feel like it absolutely should have beaten Everest and ranked higher, I think it's the best roller coaster at Walt Disney World by far, the theming is fantastic and really immersive. I do think this is the weakest version of the ride in the world with that said tho. It makes sense it's rightfully getting a much-needed renovation/refurbishment. It really lacks any incredible scene or effect that the other versions have like the amazing dynamite scene in Disneyland's! Tokyo has an awesome steeper, intense bigger final drop and a different ending. Paris is on a whole other level, on it's own island, goes underwater in a tunnel, a way higher top speed, way longer duration, two times longer track, without a doubt ultimate version of Big Thunder and a top ride at any Disney park worldwide. I would also say it's a top 2 Disney roller coaster in the world absolutely. Florida's is for sure the weakest, but still an excellent ride regeardless and again, even though there are better versions of it elsewhere doesn't mean it's still not a top ride at Disney World, it deserved top 5 easily.
We're pretty much left with the greatest rides they've ever built, but of all of them, I'd say Everest is slightly behind the others. So I vote Everest.
