i like kitchen aid and Bosh my self
bosh is good too although my wife pefers the KA dw in the way it cleans
hands down the bosh is really quiet I mean really quiet.
the bosh doesn't have a steam vent too this is nice cause the KA used to vent and the steam would run under the kitchen counter and right into the cutlary draw and condensate all over everything. very annoying
i personally have not experience with wirlpool
