The big things that stood out for us were that the Thermador simmer entails the burners clicking on & off over & over & over--gets very annoying especially if your kitchen is open to your family room vs. the Wolf that has the double stacked burners that are able to simmer using a continuous low flame. As far as the ovens, I can only comment on the Thermador--don't know if it's still a problem, but after about 5 years, the control panel slowly dies until you can't see what you have set the ovens to and you cannot see the time or timer anymore & the self-clean fried the electronics (as has been reported on many self-clean ovens). Even though the control panel issue has happened to many, many customers Thermador does not acknowledge the problem so you have to pay for the part + an authorized tech to come out 2x to verify that's what's wrong, then order the part then 2nd visit to install. Other than those issues, it bakes, roasts & broils beautifully.

Have you looked at the GE Monogram rangetop? It has the higher power burners (all burners vs. having different BTUs on different burners) + it has the double stacked burners and allows for super low simmering like the Wolf. That's why we opted for Monogram and love it so far!
