All of standalone LES activation ever in the history of human spaceflight had been successful in saving all occupants' lives.
Space Shuttle failed twice on the other hand, each time killing all aboard, and in neither cases of it its integral abort systems/abort modes did help at all.
So in theory the lack of capsule-only LES do not necessarily mean safer rocket, in the history and in the statistics it does.
