It depends on how there set up. On my truck I have on connection on the frame and two on the axle. The connection on the frame is to high because of drive shaft clearance, causing my instant center to be towards the back of the truck. This causes squatting when accelerating and weird pinion angle changes. On my new frame i'm builing, there is 2 connections on the frame and one on the axle so my wishbone will straddle the driveshaft allowing me to mount the wishbone lower on the frame putting my instant center towards the grill area of my truck. When instant center is there, then the pinion change isn't as bad, if none at all. That's my theory of why there different. From what i've researched at least. Hopefully Max will clarify.
