They're _excellent_ for wiring devices into junction boxes in construction; particularly when connecting the higher gauge luminaire wires of an overhead light to romex.
For some reason they're polarizing among electricians in the US (they carry all necessary listings for use in the US...). By contrast, they're widely accepted and used elsewhere.

They’re 8x more expensive and take longer to install than a wire nut, and they take up more space inside the device box. They’re also difficult to unterminate without damaging the lever nut or conductor.
It’s not hard to splice #14 solid to #18 stranded with a wire nut, you just extend the smaller wire a bit beyond the end of the larger wire and twist.
I’d recommend wago lever nuts to homeowners doing their own electrical work because homeowners are terrible at electrical work and the less chances for electrical fires, the better.
I’m a commercial electrical project manager in the US.

sounds like it needs a ground! /s
but seriously, what kind of junction boxes are used outside the US that these would fit?
as far as connecting a larger device wire to a smaller mains line seems odd to me. granted, i'm not an electrician, but it is pretty much opposite of all of my experiences with wiring commercial lighting and home lighting
