Bought a serie6 Bosch in 2021 and haven't had any problems with it (yet). Unfortunately it's been a while since any of these companies designed anything to "last forever".
The Bosch works well and that's pretty much all I care about.
The Bosch and Siemens appliances I've had have all given me good service. The few Samsung and LG goods I've had were all a nightmare, imagine the LED strip in your two year old fridge popping and not being able to get a replacement.
