I'll say Farm Jacks on any Jeep. I used to do lots of rock crawling and offroading. The Hi Lift or Farm Jack is horrible for changing a tire, you have to jack the body up and on a lifted jeep the suspension droop is so much that it makes for a real sketchy setup. My Cherokee is lifted 6" on 35" tires and I just use the stock little bottle jack to change a tire, even on the trail.

I did use one as a winch once, it kind of worked. The tree flex and the strap flex took up about 75% of the jacks travel but it did work, just not enough to get me out of my situation. The phone a friend at midnight option worked much better but was the last resort haha.
