Of course, Wago's and also SMD devices might stand the test of time, but the fact is that so far they don't appear to be likely candidates for longevity, but only time will tell for sure.
My house is chock full of screwed connections and wire nuts. We, too, had them, in the 70s when it was built. You can still buy them. And the Schneider/Thorsman "Torix" brand probably is the best wire nut around, but it still is clearly inferior to a 221 clamp. I have no doubt that wire nuts can be made to work, but they will suffer from slowness, high requirement for operator skill, inability to mix wire layups, space issues and rework/reuse problems. I will never again fit a wire nut if it can be avoided. The elevated price of the 221 clamps is not a problem; they are so much more convenient.
SMD, too, will work very well. It is easier to get right in manufacturing, sturdier, and better built. Just a tad complicated for ham-fisted half-blind people like me. It is much more a question if it was done well, than with which technique it was done, as long as the method is sufficiently evolved. Tek ceramic hardwire is good enough. Glass-fiber through-hole PCBs is good enough, especially if it is conformally coated. And, SMD on glass-fiber boards will also be OK. Spider-web oldschool hardwire, pertinax PCB's and counterfeit SMD components won't, but that's application error, not a problem with the concept.
Anyway,
in all those cases, it will be the caps that betray us.
