Earlier quoted context omitted.
I have trouble understanding your last sentence. Is Breville EU/Sage appliances the high quality one, or is Breville US/AU/CA the high quality one?
I m making a separate reply because I understand my answer was unclear. Sage EU is Breville US/CA/AU/NZ. Those are high quality. It’s an Aussie company. Breville EU and possibly UK (old agreements that may well predate the EEC, so don’t know any details) not the same; have never used and cannot comment.
Seems to me that the Sage/Breville have more bells and whistles (a LED light count-down, bread type selector...) whereas the Bosch seems to be a more no-nonsense one with better hardware inside (quartz glass heating elements etc)?
