The difference between Skull Mountain and the Hurricane at Adventureland in Long Island was that the Skull Mountain roller coaster uses a tire driven lift, while the Hurricane uses a traditional chain lift. Skull Mountain actually has two separate lifts with a view of the outside through a waterfall before the second lift.
The Hurricane has two separate stations for loading and unloading compared to Skull Mountain's one station.
Skull Mountain uses single position lap restraints while the Hurricane uses individual lap bars and have fewer cars on their trains.
Comapring to these two coasters, Skull Mountain is probably better, and a little more smoother.
