Old Man Emu would be by far the best, IMO. I suggest lightest spring choices that fit your load requirements. Also softest shock choices that fit your load requirements.
This is enough lift for 30x9.5R15 with no other mods, or 31x10.5R15 with aftermarket higher clearance fender flares.
If you lift more, or get larger tires than ^ that, it will not be good on road.
I'm on my 3rd Jeep. My first Jeep was stock, or near stock. My second Jeep heavily modified. My third Jeep is going to to be kept close to stock.
Also, Ranch spring rates are very stiff. It would ride very rough. Rancho would be your worst possible choice, IMO. Rancho makes some great Wrangler springs, but not XJ springs. IMO
Old Man Emu is best performer. It has 1.5" lift front, 1.75" lift rear, and a great ride and handling (for a lift, but stock ride is best).
If you must lift higher, Rusty's 3" springs are softest riding available at that height (according to spring rate specs). But I don't know about their quality. So can't comment on quality.
I am keeping my 3rd Jeep stock to have softest ride, best handling, best gas mileage, and no mechanical hassles. But if I were to lift, OME is the only lift I'd consider because it has almost as soft ride as stock, as good handling, almost as good gas mileage, and no mechanical hassles. OME is the only lift that won't cause mechanical hassles and grief, IMO.
