Bosch, Thermador, Miele are typically the recommended ones. Thermador is essentially a high end Bosch.
I guess it's because europeans typically take their appliances when they move instead of leaving them in place (as they typically do in North America).
Costco had the best pricing on Bosch in my opinion. Cheap delivery and removal of the old unit. Was really surprised how lightweight a washing machine is, but I guess it's just a shell with a pump thin metal+plastic drawers at the end of the day.
For apartments, where tenants are more likely to abuse the appliances, a plug-in might make some sense, as it would make installing a new dishwasher slightly easier, and avoid needing to cut the power on that circuit to wire up a hard connection.
