Must beg to differ. A properly soldered connection (no acid core solder, correct temp iron, proper tin/lead mix, etc) with proper strain relief (so the solder joint will not be subjected to mechanical loads) will provide the best electrical connection....
I beg to differ. A good solid crimped connector is stronger and provides an equal electrical connection to a soldered, with the advantage of being more flexible. There is a reason that car manufacturers crimp all the connectors.
I've also worked on electrical wiring harnesses of equipment being installed in Navy ships (college job), and had to be "mil spec certified" in soldering. All the connections were crimped with a very few exceptions, for those, we had to have very stringent strain relief (loop at the end, and the wire mechanically secured with a clamp).
Now, that is all based on a good crimp connector, and the typical crimper used by home mechanics doesn't do a very good job (the kind that squeezes both sides in so that the crimp takes on an "oval" shape). A good crimper "dents" the crimp into the wire.
If you are worried about corrosion, then you can pack the connector with dielectric grease after crimping and assembling the connector.
