I don't know which I like more, because ie. in Liseberg, you get a lot of airtime on the Huss space shot, but atleast I don't enjoy it, I felt sick after the ride. It's also one of the oldest in Europe, so it might not be as fun or smooth as the newer ones.
The Huss Turbo drop is great (also @ Liseberg) it goes slowly up and drops down... and shoots up again! and drops down, for the last time.
In the other hand, the space shot at Linnanm?ki is great, except that the drop after the lauch could be a bit faster.
I did also vote for launched towers in the end, because I think that droptowers that let you drop only once are not as varieting and fun than launch towers.
