I’ve just switched from a Bianca to a LMLM.
I don’t really understand the disdain for the Linea Mini. Almost feels frowned upon to buy one. It’s expensive, sure, but as with any other luxury purchase - cars, bikes, Swiss watches, furniture, sometimes the spec sheet isn’t the only selling point.
Firstly, I can’t fault the Bianca. It’s a pretty much flawless machine that in my opinion is one of the nicest looking E61s. Mine was faultless in the year I had it and if I had the money/space I’d have both.
However, what I can say now having owned both-
Bianca build quality is great, LMLM is better. It feels more robust with heavier duty metal parts, especially the case. In a home setting I’m not sure how much this really matters but it feels more solid.
Steam power is very good on the Bianca but another level on the LM. First time I used the Linea steam the milk went all over the floor… go figure.
Hard to disagree the Bianca is the ‘better’ machine though, which is why I’m not referring to my LM as an ‘upgrade’.
