The reason I always crimp first is that crimping gives a good mechanical grip on the wire. When you solder after it gives a better electrical connection. If the joint overheats the solder could melt out but the mechanical connection will remain. In an automobile vibration is a big factor as well. I always shrink tube the exposed end of the connector to help strengthen the joint.

Ditto, but I don't solder most connections other than the battery cable lugs. Trick is having a good crimper and if you solder get a good hot iron which will heat the connector quickly and not way up the wire. If the solder migrates up the wire it will be brittle and fail over time. I also shrink tube the end of the fitting and the wire to make it less flexible to avoid soldered wire fatigue.
