Heat pump dryers are in a slightly weird place in that they're boring old tech in Europe (they've been common for over a decade), and exciting new tech in the US. This means that dryers made for US preferences (physically larger, either three phase or <1500W, etc) are generally first or second models (and thus unreliable) while those made for European preferences are mature designs (and thus reliable).
The other advantage of heat pump dryers is that they operate at lower temperatures than the other types (so damage clothes less); on the negative side, they're slower.
I'm somewhat surprised anyone makes a vented washer-dryer at all.
Due to ecodesign legislation, I would assume that all machines that can be legally sold in the EU would count as "uses less water" in the US.
The dishwashers are another can of worms. My last one had an EU and a non-EU program, and you quickly learned to pick the "non-efficient" one if you actually wanted clean dishes.
My Bosch dishwasher takes 3 hours I guess due to efficiency, it seems reasonable. I didn’t go with a European washer dryer combo though (my laundry room has a vent and I’ve heard that heat pump tech still isn’t good enough).
