I've had the medium-duty OME kit (2", I think) on my '92 for between 6 and 7 years, and the ride is still excellent. I initially ran 225s, but have been running 30s (or equivalent) for over 5 of those years.
For most of that time, I was very happy with the height - plenty of added clearance without seeming very high or being top-heavy (even without the rear swaybar). the 2" OME kit with 30s looks just about as perfect as you can get for an otherwise stock truck - matches the wheelwells just right, and unless you're packed next to a bone-stock XJ, compleletly undetectable as lifted to the layman.
It wasn't until last fall when I finally let the urge to enlarge get to me - I'd been quite happy with it till then, since I was able to keep up with trucks a fair bit bigger than I was through good driving technique and superior spotters (got some real Jedi Master spotters in NAC).
What finally got to me was that the regular banging into the crossmember and frame rails all the time on the trail. This was, of course, because I was running on trails where most folks would want minimum 3.5" and 31s, if not bigger. I did a shackle/spacer add-on about 4 months ago to get about another inch and replaced the shocks with longer ones, and the truck's not ridden this nicely in a long time - my original shackles' bolts were siezed into the bushing sleeves, so I suspect they were binding up pretty badly and forcing the leaves to do most of the work. Considering I've got no rear bumpstops or swaybar, and I am not shy about flexing out the truck when I have to, it's probably something of a miracle that my leaves are still arched in the correct direction, but they are.
A full OME kit (shocks and springs) will be extremely hard to beat in ride quality.
