Had dealer installed Revtek lift with stock TRD shocks when I bought my truck used. My experience was the front easily bottomed out, and overall the ride was harsh, and got worse when the truck was loaded with box weight.
Switched to OME w/885 coils, and Nitro shocks up front. Replaced leaf pack out back (Allpro Expo leafs, as i normally have weight + canopy in the back + Walker Evans digressive valved shocks of the correct length.)
Also changed out the stock bump stops.
Highway ride, would be described as stiff, but also way smoother = better control, likely a result of better balance between droop and compression.
Significantly better control on gravel roads from both front and back end of the truck. Much less wheel hop on washboards.
Used stock UCA, and was still able to be within alignment spec with minimal castor. On full droop, UCA would touch the coil. UCA now changed out to Camburg ball joint style, and I have better castor#s, and more clearance for the coil.
