As a first time owner of any espresso machine, I am not qualified to give a lot of technical specifics regarding this De'Longhi ECP3630 Pump Espresso Machine, but I will offer my humble opinion after 2 weeks of usage. 
I love the overall appearance. Sleek in style and it doesn't take up a lot of counter space.
I appreciate that the instructions are fairly easy to follow. 
The parts are simple to remove, making cleaning after use a breeze.
The warming plate gets & stays hot.
I like that the bottom tray slides out, allowing me to use a mug or taller cup.
I do wish there was an auto stop feature, so I didn't have to turn the machine off when I have brewed enough espresso to avoid overflow.
Through trial and error, II have learned that it's better to use a medium grind espresso coffee rather than fine.
I still have a lot to learn, but as of now I would recommend it.
