Lech Coaster is amazing. I don't believe it is even possible to offer a better version of that *type* of coaster experience.
Taiga also looks very good, but for me it does not look as good as Taron. So a very similar and superior ride will (probably) be in the quarter finals.
My opinion might change once I actually get to ride Taiga at some point in the future, but Lech gets my vote for now. A truly brilliant ride.
