I don't support the use of "back stab" connections at all.. when I have wired houses I always use the screw terminals, even if it will take a little bit of extra time. I can't see how screw terminals are any better or worse than a wire nut and a pigtail though, provided it's a quality receptacle and they are torqued properly.

Right at this point, the code doesn't address the MWBC ruling regarding, three phase 120/208 network, general use circuits.
Being a retired industrial-commercial electrician, I had to stay current, with the code changes. Might be a little rusty now, being retired for eight years.
