Wiring it all up...

Well, I think I found out why a properly crimped connection is better than a soldered connection.

In a properly crimped connection, the copper strands will shift around to achieve the smallest cross-sectional area as the crimping tool clamps down. Then the full compression of the crimping tool will cause them to deform and fill in the void spaces, making the the cross-sectional area nearly homogeneously copper with little to no air voids between the wire connections. Thus, all the copper wire strands then act like a single copper wire.

In a soldered connection, there is no compression to physically force the wires to align themselves. Likewise, the solder will fill the voids between the wire strands, creating a heterogeneous cross section of copper wire and solder. This mix of materials is not as electrically efficient as that of only copper.

That's what I understand based on information that the Anderson Power sales rep sent to me.
