A properly engineered and R&D'd sway bar is not a band-aid. It is (in theory if not in practice) an integral, tuned and tested part of the entire suspension system as designed by the manufacturer. My understanding is that the OP has added aftermarket UCA's and coilovers to his truck. I would also guess that a taller wheel/tire package has been added. If that's the case, I would leave the sway bar on assuming it does not interfere with any other components.
Sway bars not only change roll rate (I apologize for what's probably improper terminology) but they also affect the oversteer/understeer characteristics of the vehicle. Most street vehicles leave the factory with a relatively stiffer front sway bar (or no rear) to keep them neutral or introduce some oversteer. Removing the front sway bar can create excessive oversteer during hard cornering. I'm not just talking about race cars. This is true for IFS trucks, radio controlled cars, Toyota Camrys...etc.
Removing the front sway bar will probably allow for better flex offroad. I have tried this with several vehicles and I found that it allowed much smoother droop, so that a wheel that might otherwise have been in the air would touch dirt. Unless your front diff is locked, though, a tire that is that unweighted to begin with will probably spin anyway.
Re: the Ford Super Duty response: I own one of these, and as far as I can tell, the front suspension design fundamentally limits any roll or articulation by design. If it were not for flex, twist, slop and soft bushings, the suspension would not be able to articulate at all.
