I have never been in a Teryx but I hear they are much better than the Rhino. I can keep up fairly good in my rzr on fast runs. no problems so far other than some things done before I got it. I have a friend that has a Teryx and with 40 hrs on it the motor is done. it could be an isolated case though. The rzrs are easy to drive do to there size and that may be something to consider as well. Jodi took the rzr out for the first time this past weekend and did great in it on a fairly aggressive run. Hope this helps
