I think the thing here is that it depends upon what sort of thing you like in a ride. For someone who loves inversions and a really intense, fast-paced experience, then I can see why someone would rank The Smiler as their favourite coaster in the park.
For me, however; I personally like a fun, smooth, comfortable, rerideable coaster that is forceful enough to provide a good thrill, but not intense enough to make you feel nauseous or grey out/black out for an extended period of time.
For this reason, The Smiler does not rank particularly highly among my Alton Towers coaster ranking (7th, to be exact); while it's not as rough as the likes of Saw and Speed, I still think it has quite a noticeable judder to it and some pronounced jolts in places. I also don't find it very rerideable, as I personally find that the sheer intensity of it has made me feel somewhat nauseous when I get off in recent years; do any of you feel like this upon getting off Smiler, or am I just weak in terms of my g-force tolerance?
Don't get me wrong, I think The Smiler's layout is a good one, and it's a sheer spectacle to look at and in terms of the engineering of it, but as it stands, my love for it as a ride experience has waned a lot over the years. This is probably in part due to my taste in coasters changing somewhat as I gain more experience, but I also find that the ride itself has grown less comfortable with age.
For those of you interested, my Towers coaster ranking is as follows;
- Wicker Man
- Nemesis
- Galactica
- Oblivion
- Thirteen
- Runaway Mine Train
- The Smiler
- Spinball Whizzer
- Octonauts Rollercoaster Adventure
- Rita
