I'm quite happy with my Miele dishwasher. It's a MOL model but it has a lot of things that I like. A water softener, a top cutlery rack, adjustable racks, etc. It even has a "tab" function and an express function.
Only thing that took some getting used to is that a normal cycle takes about 2.5 hours to run, while I'm much more accustomed to Whirlpool/Roper dishwashers taking somewhere around 40 minutes to do the same job.
The only thing I don't like about Miele dishwashers honestly, outside of the slow cycle speeds, is the cost. They're fairly expensive in comparison to other dishwashers on the market.
I've heard mixed reviews about Bosch, some people love them, some hate them.
The best personal experiences I've had with dishwashers outside of Miele was Whirlpool, (Back when they sold the Inglis brand in Canada) but I have no idea what kind of quality their modern machines have.
