First and foremost, I was very surprised to see this coaster ranked as #11 overall....
I've only ridden X2, although to my knowledge all they added was the effects and redesigned trains. While I was there they ran one train and even in January this created a six train wait. This is where I'd normally explain the rides various elements and forceful moments, however on X2 so much is happening that you don't know what is going on for the duration of the ride. From the ground it really doesn't look like much, but trust this ride is not for the weak. It's the first time since I was a kid that I was legit scared on a coaster. However this ride feels very much like a novelty to me and is a bit like a one trick pony, not something I would head for first and would skip if the line is long. Make it's your last ride of the day too, chances are you'll get a headache from this one.
Morel of the story is awesome ride, but for some reason it didn't leave me wanting more of it, the way Tatsu, Scream, or Apocalypse beg to be reridden
