The benefit is for satellite launches, the increased performance allows for launching heavier satellites. It's highly debatable if there is a higher risk to human life as well - unlike with rockets where you fuel up before the astronauts board, you don't have people approaching a fueled up rocket which could explode with no possibility of escape. Instead if there is a issue while fueling up, the astronauts are in a capsule with a escape system which should pull them safely away from the rocket if there is a problem.
