Our actual dishwasher is just a cheap Frigidaire, and it cleans surprisingly well. It is pretty loud, so i usually try to start it when we're leaving or going to bed. We'll upgrade eventually, but it does make me worry when people pay twice as much as what ours is worth & theirs cleans worse than our cheapo does.
My fridigaire cleaned fine as well. The buttons were starting to not respond any longer. Had to press several times and hope the pad worked. I did donate it to habitat for humanity and it was in working condition. I'm sure someone will be happy with it. However, we have a very open floor plan with essentially a breakfast bar separating our kitchen from the living room with TV. If the dishwasher was on, literally were unable to hear the TV. We couldn't use delay anymore because of the button issue.
Anyway, who ever said paying for the better dB isn't worth it....maybe...depends what you want. We wanted quiet. We paid for quiet.
