Unfortunately I can't help comparisons to the better and original version at Alton Towers.Inferno is just an OK ride for me. Its very small, very short, and nowhere near as fast as its bigger brother. There is nothing especially unique about the ride. And it never makes me smile like Stealth and Saw does afterwards.Does it thrill me? Not really. Ive been on lots of inverted roller coasters and can safely say that Inferno is not in the same league as Dragon Challenge, Nemesis, Montu etc. I know we're basing this on whether Inferno is better than Saw and Colossus, but its an indication of how unsatsfied I feel after riding it. I would never queue for this ride for longer than 20 minutes and I never come off saying 'that was fun'. There is nothing special about it and no talking points compared to Saw and Stealth. Saw has the uniqueness of the indoor aspect and the drop. Stealth has the launch and its the highest ride in the park. What does Inferno have? Errr its based around a Volcano. I go on Stealth for the launch, I go on Saw for the drop and beginning bit. I go on Inferno because its one of the only rides I haven't been on yet.So if no ones guessed, I chose Saw and Stealth over Inferno. But I chose Inferno over Colossus, because I hate Colossus!
