As far as wheeling, it all depends on where you wheel, where you are from etc. Wheeling to some is all rocks, some all mud, some combination, some just service/forest roads and back roads . I know of roads down home that are still legal township roads but you need 40s, lots of lift and fully locked to get through .
As far as what is best, the KJ does 96.24 % of what any of my XJs did and more comfortable doing it.
As far as fun well on a sunny day I'd take any of my old Bobtail Broncos or any of the early CJs ( short trips if tops are off ). As far as providing people with stiff necks either my 79 F150 on 38s or my 77 Dodge van on 40s . Wish I still had any of them but they all found other homes back in the late 70s early 80s .
But the KJs do a great job when you sit them up right, good skids , tires, lockers etc, just like anything else .
