I am involved mostly in industrial work. having seen a fair number of wire nuts break loose, probably from vibration, I am inclined towards the no wire nut rule for splicing where vibration is an issue. I like the crimp on wire nuts though. They don't come off.
I have seen a fair number of wire nutted splices with black tape on them where the tape was harder to get off than the wire nut.
I know of some electricians who routinely tape wire nutted splices, and then put a wire tie over it when using wire nuts in high vibration areas.
I don't like splices at all. I have spent way too much time hunting them down when they fail. But a lot of my experience is on machines where vibration can be an issue.
