We've had KitchenAid dishwashers in the past and decided to try a Bosch this time, primarliy due to Consumer Reports positive ratings.  This is a very good dishwasher, but we do not like some of the rack tines on the bottom rack that allow for bowls to poke into the spray wand preventing it from rotating.  It is also louder than the kitchenAid.  The controls are also quite complicated.  It does a great job of cleaning!
