It's definitely not AS bad as SLC's with the old restraints, in that the side-to-side headbanging is eliminated. But the trains still don't track well, so you'll still be tossed and shuffled around, and the lap restraint gets tighter and tighter throughout the course, making the brake-run quite uncomfortable.
What he said. It does seem to be a matter of opinion, but I consider it as bad or worse because of the tightening restraints.
