A couple of trail rides ago I was in Uwharrie with East Coast Trail Raiders and the only vehicle I saw break down was a Built out CJ. We came up on him with a blown tire bead. After we put that back on for him, we started out. Before we got out, he broke his rear drive axle... No one in our group had any problems.
If you want a very good comparison/discussion, PM Uvalax. He beat the crap out of his KJ. When he traded it in, he did get a Wrangler (I think). He can give you a very realistic comparison... Last I hear though, we has looking to swap out axles on it (due to putting on bigger tires) So the grass isn't always greener... Not that he doesn't have a great vehicle, I just think that some people think you buy a Wrangler and then you have everything you want/need. I know you don't think that, but some people do.
