If you own or manage an espresso establishment and are not the expert or do not have an expert to train them... why bother?
A properly trained barista with fresh, properly roasted espresso, a good burr grinder, and a semi-auto/auto trumps a superauto any day.
Point is, if you choose the machine based on the lack of barista skill... you're either hiring the wrong people, or you're in the wrong line of work.
If we were talking about the average shop, then beans, grinder, etc... really wouldn't matter because the outcome would be poor espresso, which sadly, you still get in nine out of ten places you go.
I would assume no one WANTS to be average. But unfortunately, many settle for it.
