Why SeaRAM and Sea Wolf are not direct equivalents

Is SeaRAM less effective than Sea Wolf because of concerns about its mounting and reliability?

SeaRAM is a close-in weapon system, while Sea Wolf is a point-defence missile system; their different roles are the basis of the comparison.

SeaRAM is treated here as a close-in weapon system, despite using missiles. Sea Wolf belongs to the point-defence category. The distinction is between intercepting an incoming attack at the close-in stage and providing point defence against threats to the ship. Reliability and numerical performance are outside this brief comparison.
