Right where to begin with the Smiler, 2 words ( bloody brill) top notch coaster. As for being better than nemmy, I say no to that as you have got to remember that the Smller is John Wardleys last coaster and he has put a bit of all his coasters in one ride, with a bit more as for the theming on the smiler. This is the best I seen in a long time in the UK.
Now The Smiler v's the Swarm, Swarm can not touch the Smiler, don't get me wrong the Swarm is a good coaster but way too short as you are just getting into it then its over. The Smiler is a modern coaster and it does win hands down, but nemmy still gets a score 10/10 for being the first inverted coaster, plus the trees and all have grown around it, and the roar you get from the track on nemmy is great, the only thing that will beat nemmy would be a new nemmy
3 times longer with 19 inversions, 2 left and 2 right tight cork screws before the end of the ride
and some loops indoors with a lunch into an inverted loop then up to the lift hill the cars would be stand up cars.
new name NEMESIS EXTREME
Now the Smiler in my eyes is the best new coaster so far in the last six years well done Alton towers, good job. You do know you can not build anything smaller now we will be looking and waiting for the next best thing, so keep up the good work Alton top job.
