a lot of it is because they guarantee a hit so a near miss with a nuke would work too.
russia used to rely on salvos of inertially guided missiles into a target area, without any terminal guidance at all alongside radar guided missiles, which had notorious issues themselves also.
china relies on their ballistic missiles which can only maneuver at the very end of their trajectory and have a short timeframe for finding and targeting a ship, especially if it's maneuvering and is in a different place than what was plotted and expected during missile launch.
