S:UE is a little intense, especially when going full speed, but is very, very fun. Being in the front seat as you climb the twist and seeing the plunger in what seems like within an arm's length is quite a rush.
But then there is the very back seat and having the train pause for a couple seconds on the straight spike and then looking down at the midway far below is quite a rush as well.
