Seeing how invariably similar Singapore's Transformers is to the original Spiderman attraction, I really can't see Hollywood's version being #2 on this list. I'd rather Verbolten be second; the concept is much better and looks to be a lot better than Thir13en @ Alton Towers.
I find Buena Vista Street to be much more enticing than Fantasy Forest, and I'm not just saying that simply because FF is primarily geared towards the Disney Princesses. BVS is a complete overhaul of the entrance of California Adventure, and, trust me, it is LOOOONG overdue. Minus the WDW version of The Little Mermaid ride and the Seven Dwarfs coaster, there isn't anything about FF that catches my attention. Therefore, the two need to be flip-flopped.
Even though quite a number of people aren't too thrilled about Leviathan, I'm pretty sure there are some who are mad that it's not up higher on the list for whatever reason. Honestly speaking, even though it's B&M's first 300-foot coaster, their Wing Riders are far more interesting. I'm shocked at the fact that Levi is higher up than Skyrush.
Manta....eh. Fine where it is.
X-Flight vs Wild Eagle. Nods to both for different takes on the same idea. I like X-Flight because it's essentially America's take on Gardaland's Raptor, the very first Wing Rider from B&M, and has awesome set pieces and cutout scenery. But I also like Wild Eagle because it's something I was NOT expecting from Dollywood, and it's built on the side of a mountain.
Which leaves Radiator Springs Racers as #1. And I'm glad it took top honors. Granted, Cars is my least favorite Pixar flick, and I absolutely refuse to see Cars 2, but you cannot look at the most recent construction photos of the iconic Cadillac Range:
...and NOT get excited for it. Not to mention RSR is Test Track in the American Southwest and with a second car to race with. Cars Land might not be the answer to Universal's Wizarding World, but it's the closest Disney has to crafting a pretty realized world based off an existing property. At least until Animal Kingdom opens up AVATAR Land in 2015 to combat with Uni Florida's 2014 Harry Potter expansion.
