They're terrible street cars but offroad there's really nothing more capable unless you plan to custom build a rig. If you want a smooth ride offroad it will be way to soft for on the road and vice versa. Jeeps from the factory are designed on a compromise between the two so they're not really good at either.
The build quality on modern jeeps is absolutely terrible though and the majority of jeep owners never use them for what they're intended for so I generally agree with you. But ride in a jeep that's properly setup for strictly offroad driving and you'd be amazed.
