It comes back to WHAT functionality you Want VS Need *etc...
I went from a EM6910 and thus Volumetric, was what the wife and kids were use to... *The BCF followed and she was an Automatica (Volumetric ) and the family liked it that way. *The DCM is the same..
However, I use as a Semi Automatic and use the button to start and STOP the run. *Same as others. Be it, that the operation is done via a rocker switch or a short bit of SS that is used to press an manual switch (leva ??? ) - it still a manual switch. *They also *have two types of pumps... Vib or Rotary.
Thus compared to a TRUE lever where the time / volume etc is down to the MANUAL pull of a lever and the skill of the operator. Most of the units are Semi-Auto in my view.
The Automatic are the ones that have volumetric options - Most Commercials do as it allows the operator to do other things and thus are more productive.
The Super Autos usually have a Grinder built in and the group is not accessible and the Grind / Dose and Shot is fully managed by the machine.
Thus they all have a functionality of sorts BUT what do you want / need ?
Figure out what you need and look to see what machine will deliver you the goods. *Beware of UP Selling but also be aware that the GRINDER is of SIGNIFICANT importance. *All the little extras will help... PID, Two Gauges, SS Leva, Twin Boilers, Large waste tray, hight between the Group and waste tray (cups or mugs) etc etc
As to pumps... Vibs usualy have a bit of noise but can be managed... Rotary usual means plumbed but may not... Quite when running and some say the ability to provide a more stable pressure gradent *etc... *As for me it would be the noise as my taste buds could not tell between twin unit with different pumps as to what ends up in the cup...... *( But remember... Ya still have to grind beans and that is the NOISINESS of all.) *
Then look at who can provide the best service and support.... *You might be surprised at what you settle for...
OH and remember UPGRADEitus will hit at some stage.
