WOlf doesn't make a 27" oven. Thermador has one model , but their oven quality control is shaky. Too many people with problems recently to warrant their price. Gaggenau only has a 30" double oven. Their 27" has been discontinued for 10yrs? now so finding a new one lying around will be a snipe hunt. Viking and Dacor have too much internal trouble to be focused on making quality appliances on a consistent basis, Whirlpool / Frigemore / KitAid are con artists to put it nicely So, at 27" your "good" choices are Electrolux , Bosch and GE Monogram in no particular order.

Take it from me what CR says about Thermador wall ovens is absolutely true. I have purchased two 30" C series Thermador ovens and am getting ready to replace the one that was existing in the home we purchased last year. Loved the way my Thermador's cooked, baked, and broiled but had to have them repaired. It seems there is insufficient insulation between the oven and the electric control panel and when you use the self clean, over time, it causes the control panel to fail. This is a minimum $1,000 repair. I live in Dallas and there is only ONE company in this area that will service Thermador ovens because Thermador service dept is so difficult to deal with. My regular service company which is efficient and costs are fair told me they stopped servicing Thermador ovens for that reason and three others I tried said the same thing. Both my Thermador ovens needed the control panel replaced within three years of purchasing and the one in our new home could not pass inspection and had to be repaired by the seller before we moved in - yep it was the panel and it cost them $1,200. They didn't cook and it was an older oven. The space we have for the wall oven is 27" and after looking and looking and doing research and reading here and other web sites with independent reviews by actual owners we have chosen the Miele Master Chef Classic Series which has the Novatronic controls which everyone seems to love. This choice was made in part because of the rotisserie feature which we do use quite a bit along with other features we liked and which were well reviewed. It was more expensive but we went with a straight Microwave which suites our needs and we chose the Electrolux Ei27MO45TS microwave which meets all our needs and was well reviewed. Went with the Miele warming drawer because of the match and the fact that it was the same price as most other warming drawers we were considering. We stack our ovens in an unusual way which we really like with the actual wall oven first, then the microwave, and then the warming drawer. It is logical to us because the heaviest items come out of the oven and having it at the top means no stooping and it's easier on the back. We usually only use the warming drawer when we entertain and to reheat leftovers which it does so much better than a microwave. Still trying to decide on which Fridge and Freezer columns to choose but that's another forum

My double oven just died after 14 years. Cannot fix it because I have to replace the "Brain" plus the self-cleaning lock and convection fan. To replace the brain would cost about $400 for the part. I can probably fix it but after 14 years, I am better off getting that Gaggenau that you all talk about. However, there is no doubt that two ovens would have been more reliable in my case. In my case, the damaged was caused by the self-cleaning function. The upper oven was used twice-daily while the lower level was used once a month. But I cannot complain, I did get 14 years out of it!

I’m not sure of your models, but as a Dacor owner I can say I’m happy with that brand. The ovens run true to temperature and cook pretty evenly, and the convection works well. Mine’s a range, and the burners are terrific. I especially love the “oversized” 6 burners on the 48” range. A removable griddle that fits over the middle burners, so you still have a griddle when you need it, and the size of the burners means you’re never squeezing and juggling big pots.
