Everest wins this one easily for me. I just don't find the ride experience that enjoyable on RRR. Outside of that though, Everest is better in about everyway. The theming of it is amazing, from the museum queue with the gardens, to the mountain, even the shrine on the lift hill seems packed with stuff. RRR has a very basic queue, and the only real theming it has is the onride audio choice. Everest is also very smooth. It doesn't have the same intensity for better or worse, but it still has the height and speed some for thrill.
