I have an espresso machine (or had, recently sold) as well as a moka pot as well as many other coffee making gadgets like a V60 and an Aeropress. They all make different types of coffee and are not comparable. Sometimes if you want true espresso you need to use an espresso machine.

Moka pots don't make espresso though. True espresso requires ~9 bars of pressure to make. Moka pots can create at max 1.5 bars (though optimally it would hover between 0.5 and 1 bar).

So while they make very good, rich, full-bodied coffee, it's just not espresso.

But they make horrible coffee, and can by design only brew at the wrong temperature.
