The experts say no because the solder creates a "hard spot" which can
work harden and break after repeated vibration, same as using solid
copper wire instead of stranded. There is nothing wrong with a good
crimped connection if it is made properly and kept dry. One of the
secrets to keeping it dry are to always install them with the wire
pointed downward, and/or have a drip loop within an inch or two of the
connector.
