Fresh grinding right before brewing matters more for taste than almost anything else. A built-in grinder saves buying a separate one.

More steps let you fine-tune extraction for different beans. Below about 15 steps, dialing in espresso gets hard.

Dual boilers and heat exchangers can brew and steam at the same time with stable temperature. Thermoblocks heat fast but drift more.

Wetting the coffee puck at low pressure before full pressure evens out extraction and forgives small tamping mistakes.

Preset recipes such as latte or cappuccino at the push of a button.
