Looks like a clear win for Expedition Everest. Curse of DarKastle is good, but nowhere near as good as its Spiderman counterpart.. and you can't beat the originality and track changes of Expedition Everest.
Also, fun fact.. Curse of DarKastle blue-screened last time I was in it. That was interesting.
Griffon is a one trick pony that does the trick twice. Fun yes, best coaster? absolutely not.
