The actual amount of contact area in a soldered joint is much higher though. The crimped joint will have the tangent of each strand on the connector, for lots of tiny little contact points. Soldering, you can take the same contact points but also add the higher resistance solder for all of the area in between, dramatically increasing the cross sectional area of the contact.
