at that lift height i recommend you go crossover, but it may very well not feel as great as it could. when leaf springs get that much arch in them, they become a less effective control for the lateral movement of the axle. so when you apply steering input it will also push or pull the axle out of centerline of the chassis. you feel it as a sort of bump steer. the taller the spring, the worse the effect. that is why at those lift heights sometimes the push pull with a stack of corrections feels better. i think push pull is the better system if you can keep from stacking to many corrections. as it gets taller, the geometry that made it so effective with lower ride height goes away.

so my caveat for the recommendation of crossover is that you also go with a track bar. properly engineered to work with the crossover steering it will eliminate the wander from the spring flex and allow for true bump steer free crossover. it will also likely help the truck feel better on the road.
