Between myself and 2 adult daughters we have owned them all.....But the top of the line Bosch is unbelievable by comparison to all the brands we have owned. So quiet, I don't know it is on. So clean, and I don't prewash/prerinse. I do scrape food chunks off for my chickens, but my hubby just drops his dish on counter and it might harden before I move it to the dishwasher for scrubbing. It has a great 3rd top tray for spatulas, and small what nots that I now can't live without. The cycle is 2 hours and 18 minutes....but it is so quiet, I don't care. I have had mine for over 10 years, and I will replace it with another Bosch the moment it decides to quit working. ( I have not had to replace a wheel or bracket or anything on this workhorse.)
