My advice to you would be to go with the Rancho 9000XL shocks because:
1) They have adjustable settings to hone in on what you desire for ride. (Avoid getting the in-cab remote adjustment feature though...$$$ and many here commented on it not functioning correctly!). The Rancho 9000XL shocks displayed on Independent4X.com show the manual type adjustment "knob" on each shock that you hand-turn to adjust the shock ride.

2) They offer the added off-road ability you said you want. As far as on-road ability.......I had to work my "butt" off to keep up with NocturnalVX in Denver with him running Rancho's and me running O.E.M.
The only other shock I can think you might like would be the Old Man Emu...but, I've only read one other person that used them here and this is what he had to say:
Hope this helps!
