From a production standpoint, crimped connections are superior - they're quicker to make, easier to inspect, and just as strong. A proper soldered connection is much more labor intensive, for not a lot of benefit.
One place where soldering *is* better is where the crimping operation breaks the tin or silver plate of the joint, exposing copper to the atmosphere. A soldered joint leaves that protective surface intact.
