The bosch looks smaller, but it still hold 14 place settings.. It has all the same adjustments as well... racks go up and down, alot more flexability with the tines etc... Its a tad smaller but it still holds just as much as the KA did... Its so quiet and cleans much better. Energy is also saved as well! All in all, the Bosch is better then the older one... Ours cleaned but it started to leave gunk on the dishes... Yuck! The bosch also get VERY hot (161 F ) and uses such little water.
I work at Sears, alot of people dont like Bosch because they dont have a hard food disposer... It has the trap, but what people fail to understand is that it is in fact has a self cleaning filter. The water gets so hot and the water pressure is so great that it dissolves everything and is then purged by the pump. It doesnt chop, but Bosch calls it "Pulvarized" After listening to a cycle, you hear the pump draining all the sediment in the trap every so often. Pretty neat...
So yes, I think that its a better machine then the old Kitchen Aid... Then comparing a new KA to a Bosch... It comes down to: Do I want near silent, or ProScrub (same thing as Kenmore TurboZone)
I could go on All night about the differences and similarities between all the major brands!
