Ground coffee, especially if freshly roasted and ground, results in much better quality coffee than the kind of results you get with pods or capsules.
It comes with a commercial style steam wand as opposed to a pannarello steam wand. These are harder to master but can allow you to produce better, richer milk froth.
A 58mm portafilter is the most common size in the industry, offering a greater range of accessories to purchase such as portafilter baskets and tampers.
One of the most important aspects to pulling a great espresso is the amount of pressure used. Aspects such as how tightly tamped the portafilter is can affect the pressure and therefore the overall quality of the extraction. A pressure gauge helps you to adjust your process to achieve a perfect 9 bar of pressure.
It has a steam wand, which allows you to make steamed/frothed milk to create other drinks from an espresso base.
With a cup warmer you can heat the cups before pulling your espresso so that it doesn't go cold quickly, which affects the taste and quality. It also means that you don’t have to manually heat them using hot water.
Steam wands are a fairly common source of burns when using espresso machines. An anti-burn steam wand has a lining inside that prevents the wand from getting scalding hot.
A hot water outlet is useful as it can be used to heat cups, as well as making americanos, long blacks and teas.
The water tank is removable, making it easier to refill.
With a larger water tank you don’t have to refill it as often.

The coffee machine can connect directly to the water supply. This ensures you never have to refill the machine with water.
A higher capacity boiler means that you don’t have to refill it as often.

A 3-way solenoid valve relieves the portafilter of pressure and moisture after the extraction. This produces a dry puck which can easily be removed afterwards. It also means that you don’t have to wait for the pressure to equalise, so that you can make back-to-back coffees.
With a pre-infusion function you get a low pressure of water before it ramps up to around 9 bar of pressure. This gently expands the grinds to get a smooth extraction and to help prevent channeling in the cake.
With a double boiler or heat exchanger system, you can brew and steam milk at the same time. This has an advantage over single boiler machines where you have to wait between brewing and steaming for the temperature to adjust.
