I rode TOT when it first opened and has less restraints (I think it was a lap bar over the row?). After that, I swore I'd never ride it again.
In March DD15 convinced me to give it another try. I was terrified the whole time, but survived. I wouldn't chose to ride again, but if I was traveling with someone who never rode it before and wanted company, I'd suck it up and go.
So I'm not a fan, but it's not the worst experience ever either.
