Until recently, most water heaters were usually set at 140 degrees which met the dishwasher requirements. When energy got expensive, to save money most people turned down the water temp to 120 degrees or cooler. Which is not hot enough for the detergent to work well. (End user created problem)"look at what people are complaining about. Most issues are typically not appliance related but how people use them."
Which is stepping backwards.
120 used to be the dishwasher's heating element's job. It doesn't "save" anything to move operational requirement to end users. I see this poor engineering at work also, mainly from EEs writing software. My absolute least favorite: "... will force the user ...". Engineering, make it easier for users, not the engineer.

Mr. tells me his relatives in India have 70 year old refrigerators still running. Friends tell me some of their appliances are failing in less than 5 years.
I agree with your suggestion to not go with a single brand but go with the best one available regardless of brand. I've had four dishwashers so far, Roper, Whirlpool x2 and currently have a Bosch. The Bosch wins hands down.Fords are better that Chevys (IMO).:thumbup:
Use Consumer Reports and get informed, unbiased ratings. I would not stick with a single brand, go with the best ( within you pocketbook) for each appliance.
