Why should that be?. Not that you'd what to do both normally;!...

Firstly, many solder joints are not well done, secondly the solder
wicks up the cable and creates a short rigid length of cable going
beyond the neck of the connector. The heat partially embrtittles the
cable and its insulated coating and the wire breaks more easily at
the "hard spot" at the sharp solder boundary. In addition the flux
can cause corrosion.

Almost the only reason for failure in crimp connectors is the use of
incorrect tools such as the silly pliers supplied with cheap crimp
kits. You even get some people trying to attach crimp joints using
pliers or wire cutters.

For high current (several hundred amp) cables it is usually better to
cut the wires to length and pay someone with the right hydraulic tools
to fit the terminations.
