When we built a house 15 years ago, we declined all the "premium brand" kitchen items in the builder's spec, went to Choice (consumer advocacy and testing in Australia) and picked from the best-rated dishwasher, oven, stove top, rangehood, etc. All worked well and we were happy with all of them. On another occasion, the recommendation was Miele (vacuum) but not for any of those kitchen items in our case.
