New appliances within the past year for my daughter and I included Thermador gas SS cooktop, Thermador double ovens with convection, Bertazzoni not self cleaning standing oven with gas ss cooktop, Kitchenaid gas ss cooktop, Kenmore electric SS not convection double ovens.
Bottom Line: Thermador dishwasher already had to have a repair
Thermador gas top is wonderful but the stars can get out of line and be a nuisance. I'm concerned about the burners already. Oven doesn't regulate temperature enough for me but my daughter loves her Thermadors and they look great. It has the best of the simmer burners.
Bertazzoni is the least convenient and it doesn't regulate temperature or heat evenly. It doesn't simmer low enough for me without my adjustments. It is manual cleaning and doesn't have a timer. The best thing about it is the look and the quality of the SS which is fantastic.
Kitchenaid must have an inferior quality to the ss burner ring which is not easily cleaned and has discolored and now has brown burn marks. The rest of the ss cooktop is fine. I like the layout of the high speed burner in the middle and it is also the simmer which is not low enough for me so I use the left back burner on very low and that seems just okay.
The big surprise is the Kenmore 27" double ovens. I bought the no frills but really good looking one. I just didn't want to spring for the expensive ones that looked great. Anyway, it doesn't heat the house, it preheats quickly, it cooks evenly and I haven't used the self cleaning yet. Timer and regulator are very good too. BTW, a friend bought the Jen-Air gas cooktop and had the same problem I did with the Jen-Air I got rid of. It just doesn't cook fast or hot enough.
