My guess is that at fairs the rides make money per rider. In order to attract riders and even attention from the midway, the crazier the program the better.
I could easily fit a robo arm like the ones Lego has at a few of their parks. The variability in the ride would also make me less likely to get bored with the ride.
That's the great thing about this burning question. It's vague enough that you can make it what you want it to be. For me it was better ride experience.
For which I want to visit it would have been the other since SDC is far better than any six flags park.
