The X is a great rig. I have had 2, a gasser and Diesel. The Diesel is far superior. My Diesel got 18 mpg at 75 mph from Phoenix to Socal when I bought it bone stock. Since, with the 6 inch lift and 35's I still get 16 mpg highway at 65 mph. The X has a solid axle which is much stronger and easier to lift. The Burb will ride a little better, but the X rides fine. Niether is perfect. On the pre 03 X's the tranny is the weak link, if you can get a good deal on the ESP I would go with it. If you kept your vehicle a long time the Diesel X would outlast the gasser Burb 3x over. I say get the X. Good luck.
