Just want to chime in as a "ride wimp"... I absolutely LOVE GOTG and liked Tron enough. LIke all the PP's said, neither is "rough" from a jerkiness standpoint. But as far as "rough" goes meaning "intense", I think they are both about equal. But GOTG is just so fun. I am so glad I was brave to try it and have been on now 8 times over 4 trips since it opened! I do sort of close my eyes at the vortex part only because I read on here that part is what makes people motion sick. Anyway i highly recommend GOTG, and if you can handle the takeoff Tron is cool too. Just too short of a ride and I don't love the seats.
