If your'e just going to be using them for aesthetics and getting in and out of the Jeep, they'll be fine, but if you are going to be playing the rocks you want something tub mounted. Avoid frame and body mounts when getting rock sliders that have to be functional to protect your Jeep.
If you use the one's you linked to and add a 1.25" BL, it's going to create an unsightly gap. I've had one before! They look suck. You can't usually mount them above the body lift. I tried that.
Just do it right the first time. The cheapest tub mounted rock sliders for function (again, if you need it) are TNT and JCR. Most get Poison Spyder or some other stuff that is sub-optimal design. My .02c
Yeah, mine's only a street Jeep that may see some dirt roads once in a while. No rock crawling for me
