Synthetic winch rope and steel cable both have amazing qualities that make them better suited for certain situations.
Synthetic rope is just as strong and sometimes stronger than the metal cables.
Synthetic rope does not kink, or twist when it is being spooled, or put under a strain.
Synthetic rope is safer because it does not recoil and cause any potential harm if it breaks while pulling a load.
Synthetic rope is lighter than the steel cable and the rope is water resistant. It does not rust or corrode from exposure to moisture or high humidity.
