If you are going to be adding lockers, tires, t'case gears, etc to an X....then yes, I think the Rubicon is worth the money. The rubicons are pretty much ready to go out of the box, where the X will need some work before tackling some of the moderate to difficult trails. IMO, it really depends on what kind of trails you are going to be on, and if you do your own wrenching. Anyone priced a pair of ARB's and the install recently? That is half of the premium of the rubicon right there!
