If you're soldering, that does a better job than any crimp.

It doesn't do as good a job with stranded wire as a good crimp. ...

Crimped connections are used in aerospace applications.

A good mil-spec crimp uses four-point indentors with a ratchet tool
around a seamless barrel, and the wire size and barrel dimension
are VERY well matched. It isn't practical to use those systems for
jackleg repairs, so simple U-crimp fittings are what most hobbyists
see.

Best U-crimp tools are from AMP, Klein, maybe Molex. There are
lots of dollar-store chromed pliers that won't do it right, and lots
of barrel/wiresize mismatches possible, but generally the tools
and supplies at the 'high' end are good, and the dollar-store ones
give them ALL a bad reputation.
