Screw terminals are nice for anyone who designs and builds a printer from scratch and doesn't want to pay £20 or so for for a crimp tool. For kit makers and anyone with a crimp tool, plug-in connectors are better. The kit manufacturers benefit by reducing the possibility of miswiring, and.users benefit from being able to disconnect the wiring from the electronics quickly and easily (and again reducing the possibility of miswiring when they reconnect). I removed most of the screw terminal blocks from a Duet board I received and replaced them with header pin strips, to make the wiring of my Mini Kossel easier. I'm not sure whether to go for pin headers to keep the cost down, or locking/polarised Molex connectors that cost a little more. For anyone who really wants to use screw terminals, I guess I could offer a board with the connectors not fitted. I do plan to use screw terminals for the heated bed, hot end heaters and power connections.
I like this attitude. And also favour Molex KK over plain pin strips for the reason you mentioned: disconnect, connect and be sure it works the same as before. Crimp pins get soldered here, works fine without a crimp tool.
