Wilwood kit vs Dr Diff Wilwood kit, help??

I am going to run Wilwood front brakes on the duster who has run the Wilwood kit and who ran the Dr diff kit as the Dr Diff kit uses a standard mopar rotor from a later 78 model car and uses custom steering knuckle as opposed to the Wilwood kit where it uses hubs etc to adapt the kit to standard steering knuckle

Any pros and cons between the two as similar price points
