My Rhino had some of the best long travel I have ever tried so not a good comparison. I don't drive other peoples rides so i haven't driven that many Utv's aggressive like I have my Rhino and Cat. But i do have many hours in all different rides, driving and passenger.
I will tell you the difference I noticed. The cat seems like a short bus, not top heavy but you sit up higher so that took some getting used to. The suspension is really awesome especially for stock, The rear end i bottom hard often. Its tightened all the way down but It still slams on drop offs, bunny hops off stuff and in the whoops of course.
I drift corners allot more in the cat, you have the power to really steer with the rear end. If I am going into corners to hot, like in the wash, I can slide into the corner sideways and gas it out of the corner, more like a bike or quad.
I would say for stock suspension i give the cat a B+
I would give the stock Rhino suspension a B- at best
I would give the stock Rzr S suspension a B+ maybe A
The front works great, I just cant get the rear to match, i have had no tie rod problems or spindle problems. i have bombed this thing threw the Dunes, lots of good air time, it dunes really well, jumping into big dunes does really well the engine really helps, rides allot like a quad.
Its very nimble for a big UTV. its always on its toes it feels like.
I want to add the huge brakes saved my azz many times.
