CoyoteOldMan I can’t compare to Bianca, but I have a Mara X with flow control (Coffee Sensor) and love the machine. I only make a single drink 99.99% of the time, so don’t feel the need for a dual boiler (2-3 milk drinks is also not a problem, but I rarely need that capability). Temp control and stability is more than I think I need, steam power is never a problem, workflow is perfect for my needs. I can’t think of anything else I would like the machine to do that it can’t, or any feature that is missing (for me) that I would get with a Bianca.
One of the crucial things for me when choosing the machine was (and still is) the small footprint. Bianca is bigger, so if someone offered to swap my Mara X for a Bianca at no extra cost, I would probably politely decline (although I am sure it’s a fantastic machine). I may well be an ignorant fool, but at least I am happy. :)
