Well, normally I'd recommend the RE 2" BB. Very economical and very complete with a lot of flexibility for about $200. Then invest in other things such as armor. It rides very close to stock but is marginally firmer. I was concerned about ride quality a lot but I barely notice a difference.
If you wanted a much more plush ride then the OME lifts would be a possiblity. I think they are about three times the price of the RE 2" BB but the ride quality is supposed to be great, better than stock. Though many people aren't convinced the OME lifts are 3 times as good.
However, after seeing the performance of the Unlimited on the trails last weekend you might
want to consider a taller lift, around the 3"+ range. The Unlimited that I ran with was great, very impressive but I could see where the break over angle "could" be an issue. I'm not as familiar with taller lifts but many on here have said good things about the RE 3.5's. Talk to Rubicon Express to see if their standard TJ kit will fit the new Unlimiteds. I don't know why not.
A note about the 3.5" RE kit, there's two types: a standard 3.5" for $540 and the 3.5" superflex with replacement control arms that have high flex joints. The standard kit should ride smoother because of the rubber bushings. Also, the ride depends a lot on the shocks you get. Neither of the 3.5" RE kits come with shock sot that's an added cost but allows you to select a softer shock.
Another note about the 3.5" lifts. On a standard TJ, once you go above ~2" of suspension lift you either need t-case spacers to lower
your t-case again OR get a SYE and new rear drive shaft. However, the unlimiteds have a longer rear driveshaft so the driveline angles may not be such a big deal. Something to check on.
FYI: Here's a pic of an Unlimited wiith a 2.5" OME lift and 32x10.50 Supeswampers:
I guess the big question is what do you want to do with your Unlimited? Hardcore trail running, fire-road exploration, moderate trail runs? Figure that out and then go from there. A 2" lift will get you into a lot of places with the Unlimited and they'll fit a 32" tire. If you want to keep your stock rims, consider the Spidertrax wheel spacers
for some added clearance for 32x11.50's.
Bottom line: I'd say save up a little more and go for the standard 3.5" lift with good shocks.
