I can't believe I lasted so many years doing various DIY electrical jobs around the house and shop, using mostly a bunch of improvised connections, pigtails, screw-on connectors, twist-on wire nuts, and lots of soldering, and only recently started to crimp my own ferrules and began to use Wagos (not necessarily together). What a pleasure both of those are! To think my life could have been sooo much easier all those years. I get a kick especially out of crimping the ferrules. So much more professional-looking than loose strands. I even got both a square and a hex crimper to use depending on the shape of the receptacle. And OTOH I did a bunch of research about how many amps the Wagos will handle beyond their rating. Very very impressive. Seems like they are the standard in Europe now. If you haven't already, have a look at both of those.
