Are you a clothier serving coffee, or an espresso bar selling duds?
Assuming the first: Where are you going to find the employee time for barista duties which go with an HX and stand alone grinder? There's a loss of quality, but I don't think many customers would notice; and do think you'd make your commercial life much simpler with a super automatic.
Otherwise, the Evoluzione is a very nice machine, possessing all the virtues you've mentioned. It isn't unique though. Almost all espresso machines of that type and class are assemblies of a fairly restricted group of common components. Consequently the choice is usually between "equally suitables," with no "best." Indeed, there are multiple "plumb/no-plumb" choices.
The important differences tend to be price and style. Although, if you're not plumbing in, drip tray size counts for a helluva lot, too.
Plumbing in makes many HUGE positive differences. The absence of smell and overflow from a neglected drip tray are just two of them. If the expense of plumbing isn't dispositive, it's a good idea to do it from the beginning. You can always cap the supply and drain if you decide to remove the machine and sell it off. Plumb/no-plumb makes great sense for someone worried about moving to a smaller flat with a hostile landlord, but not as much for you.
