Micro 4/3 body with the Olympus 45mm 1.8 is the bees knees. The glass literally slaps. I've had people IRL gasp when seeing photos the thing produces, especially if they haven't touched a real camera for a few years. Yes the iPhone Pro cameras are good, but you can't beat physics.

But... the best camera is the one you've got on you, so I can't blame anyone for the convenience factor, I also take pictures primarily with the iPhone.
