@ Niall, Remember this one thing, It's your License on the line when you wire homes so Electricians will use whatever makes them comfortable, IMO I would not use these for JBOX wiring thats all.
Well I guess for me I never really trusted push in connections for high current connections, especially since I've seen some push in outlets with toasty neutrals.
I personally never use those push-in connectors. i use wirenuts just becuase I have so many and I can use those with stranded wire. Push-in connectors are only supposed to be used for solid wires. As for grounding this, if the fixture is grounded, wouldn't this be grounded too because the conduit is metal?
It's not conduit, it's armoured cable. As a matter of fact the metal jacket of armoured cable was used as a grounding path for years, however it is now not allowed. So yes the box may be grounded but I wouldn't take the chance.
I don't "back-stab" recpetacles but always use the screw terminals instead. For multistranded wire you should NEVER use wirenuts or screw directly to terminals but instead use these little things called crimp connectors for multistrand. For single-strand, I use wirenuts but these sound like a good idea...my only question is are they removable/reusable?

Nothing really wrong with using wirenuts with stranded wire if you twist the wire neatly. Crimps are a pain to undo and sometimes you can't and you have to cut it off which shortens the wire. For terminals, the better ones that have a plate under the screw will work fine with stranded wire too. I have some of the push in connector but I mainly use them for extending fluorescent ballast leads.
i always twist stranded wire before wire nutting it and it works fine every time. i prefer to work with stranded wire since if i want the ware to be thinner i can just break off some of the strands lol.
