IMO, the drop on Everest provides more intense feelings than RnRC. You definitely feel the G's in the backward and drop areas, and that's what gets a lot of people. Yes, you go upside down on RnRC but the first two inversions, I sometimes forget about just because I'm still enjoying the launch feeling. And the G's feel more like the "pin you in your seat" kind, not the "what is my stomach doing" kind.
However, a warning for RnRC. I find that at my 5' height, my ears are the perfect height to bang back and forth in the restraint. So I often come off the ride with a headache, and never have the "oh, let's ride it again!" feeling.
