I just put on the TF coil leveling kit and really enjoy it. The big difference is around turns, where the coils really keep the jeep tight, while the pucks that I had before from TF would not be as tight around corners.
If you are just going on dirt roads, a leveling kit maybe better for you. You get a great look, and do not have to worry about replacing control arms or anything. You could put on an adjustable trackbar, but I have found it is not essential.
