There's plenty of forceful and rough coasters on the planet that run rings around The Smiler.
Out of interest, what are some examples you can think of?
People have different tolerances, which is why some people can cope with extreme rides and others can't. You have a stronger stomach than other people when it comes to Smiler.
I'm yet to ride Smiler, and I've always been worried about if I'll be able to handle it.
The best advice I can give you is to try it once. If you love it, then great! If it’s not for you, then just don’t do it again.
There is a big difference between an intense coaster than you can get off feeling like you had a great time and enjoyed a mixture of different forces including some really forceful moments, compared to a relentless feeling where its more about the duration of the ride.
Coming off a ride dizzy isn't the sign of a good ride. Coming off any wanting to ride again because it was so much fun/scary is.
See, I’d also say Nemesis mainly relies on positive g’s as its main party trick (it doesn’t really have any negatives or hangtime to speak of), but the way in which it uses them is one I much prefer to the way Smiler uses them. It does have moments where it gives you a bit of a break from them, and they don’t feel too overpowering. If the ride’s running poorly, then these sections can admittedly feel a bit sluggish, in my opinion, but if the ride’s running well, then these are very much valued.
Personally, my favourite coasters are ones that offer more negative g’s as well as just positives. Looking at my top 10 (in my signature), you might notice that many of the rides in it, especially towards the top, have at least a decent degree of airtime, hangtime or negative force. I know Swarm initially looks like a red flag, but I actually find Swarm to have absolutely blissful hangtime, as well as some surprising kicks of negative g in places! Swarm is quite a forceful coaster in sections (notably the helicopter helix), but it’s not intense enough to detract from the ride for me; Swarm strikes a nice balance between thrill & rerideability, in my opinion!
However, I find that sometimes, one element or section of a coaster is just so, so intense that it still makes me feel strange and detracts from the rest of the ride. For instance, a good example of this is Manta at SeaWorld Orlando, where the sheer intensity of that pretzel loop just ruins the rest of the ride for me, and the raw intensity of the section with the loops on Olympia Looping.
I’m yet to find a coaster that has too much negative g-force/airtime for my liking, but I think positives are something that I only really like when used in moderation. I know this might not be the case for some, but I personally find that you can definitely have too much positive g-force on a ride.
