I have also never had a failure of a crimp after it passed the pull test.
ALWAYS CRIMP but there is a different reason.

The O2 sensor actually pulls in atmospheric air through the multi-strand core of the wire! If you solder it you will plug the wire up.
I first thought the explanation was bull until someone gave me a link to a document on Bosch's website where they explained exactly why you must crimp.
