I bought a Bosch Silence Plus 48dBA diswasher for the lower noise level. It is quiet.
However, the interior design is poor. They were so anxious to boast that the dishwasher could hold 12 complete place settings that they designed it just to hold plates - not everyday pots and pans. The slots for inserting plates are so close together and slanted that you can't set anything but plates in them. I straightened all the little pegs to be straight up and down, but now the plates lean forward.
I used to just run the machine a couple times a week for just the two of us. Now I have to run it every night because I can't fit anything in it.
Energy efficient? I think not!
