Having owned a Rough Country lift on my previous JK, I would never suggest their lift to anyone. Anyone who says they ride great is only saying that because they haven't experienced anything else.
As Chris mentioned above, they ride terrible, which is mostly due to the cheap, low quality shocks. Rough Country is also known for predatory and deceiving marketing practices, such as pushing "dual steering stabilizer" setups.
Stay far, far away from Rough Country. They are right down at the bottom with Skyjacker.
