Bosch. Best dishwasher I ever had, hands down (at 2 different houses). The dishes came out spotless every time, and it was nearly silent (I know you say you don't care, but once you've had a silent dishwasher, you wonder why you ever put up with a noisy one).
The house we just bought has a GE. Meh. I wouldn't recommend it. I'm forever having to run things through again because they didn't get clean the first time.
We have had KitchenAid dishwashers at 2 houses, as well. One thing you should be wary of on KitchenAid dishwashers is that the door is very heavy (you wouldn't notice normally because it has a hinge that makes the door open and close easily). However, the hinge mechanism is made of PLASTIC. We had to replace the plastic hinge on each of our KitchenAid dishwashers, and on one of them we had to do it twice (it's quite a chore, too, let me tell you). For that reason, I wouldn't recommend a KitchenAid, even though it did clean the dishes well.
