Linea is a dual boiler machine, quite different to a HX machine.
What good about a dual boiler is the temperature stabilities.
I would say my VBM is considered as a prosumer machine.
Just like the other HX machines, it has just a single, but thx to the HX sytem, it can brew and steam at the same time. There are quite a few commercial machines use the HX system as well.
In terms of the steaming performance, I guess it depends on the boiler size and the pressure of the boiler.
