Thermador CMT-21
These great ovens get my vote as the best wall oven ever made for use in a home. I have had mine since 1987 and it is fast to pre-heat, energy efficient [ more so than any new oven built today ] it vents outside so there is almost no heat and odor even during cleaning.
Best of all it has the added power of microwave energy that can be used with both baking and broiling as well as alone.
Add in excellent non-electronic logical controls, gasket-less doors and a self-cleaning cycle that really works.
It is certainly the best oven I have ever seen or used.
