What's the difference between semi-automatic and super-automatic espresso machines?

Semi-automatics (like the Breville Barista Express) require you to grind, dose, tamp, and start the shot manually, giving more control. Super-automatics (like the Terra Kaffe Demi) handle grinding and brewing at the push of a button, trading control and shot quality for convenience. Specialist coffee subreddits generally favor semi-autos for flavor; super-auto owners prioritize ease.
