Seriously though i've owned both...obiviously the 48" is easier to store and I started with one. But after axle swaps and larger tires I found the 60" is what I needed to get my tires off the ground! But depending on the lift you have now or what you plan to have....i found that they 48" limited me too often and got scary as hell trying to get it up there to change a tire. The 60" was more stable for me. It just all depends.
Not a YJ guy, but i'd vote for the 48" because of mounting it. I personally took and drilled some holes in my rear tire carrier and run some bolts through it, then mounted my high lift on that.. works great. Its more of an ornament then any thing.. works really good for a handle on my tire carrier too.. i use my winch MUCH more. But i actually got to use the jack yesterday to help a buddy change his tire on the trail.. first time ive ever used it on the trail
"48 is just fine, really dont think you will need to lift your jeep "60 off the ground. if you were closer i would sell you mine, it just sits in the garage collecting dust since my stock jack works just fine with my "5.5 of lift and "35 tires.
Mine just sits in the corner of the garage too. I would save your money for something really useful. If you ever did need one, someone else will have it. I have never needed one wheeling. I tried jacking up my Jeep with it once and decided it wasn't a good idea and just used my floor jack. I use my stock jack to change my 35" tires too.

Keep in mind that some bumpers are goofy-shaped and don't allow you to get underneath the body very easily... for example, my front bumper has a tube that sticks forward and the only way I can use the jack from the front is to lift from that hoop. At that height I can only get a few inches off the ground. Fine for the garage, not fine on weird uneven terrain in the unlikely event that I need to lift my entire front end (maybe if my diff was stuck in a rock and I couldn't get off). It hasn't been a problem for me yet and I have the 48" hi-lift, but something to think about. If you can store the 60", why not get it? You never know...
