This doesn't exactly answer your question, but I went from Rancho RS5000 shocks to Fox shocks (no-remote), and the difference was beyond night and day. The Rancho RS5000 absolutely sucked. The Fox has been amazing.
Note: there is a huge difference in feedback from the RS5000 and the RS5000X. That X at the end apparently makes all the difference in the world. But my experience with the RS5000 has soured me from trusting Rancho. But there is a ton of good feedback from RS5000X users...
So shocks definitely make a noticeable difference in ride quality.
I would, however, heavily consider trying to sell those E load tires, and get C load.
You will likely take a bit of a financial loss, but consider how often you'll be driving the Jeep and what your comfort is worth.
