Both are new so no reviews are out there. Wolf has had ongoing issues with the blue enamel chipping and they made the M with a removable bottom now. I think they are hoping this will be the fix or at least make it easier to repair.

I just got a new BlueStar range top (which I love) and wall oven (30" electric with french doors)... which I would like to love but from the moment you turn it on there is a very noisy blower which stays on (separate from the convection fan: tek support guy says this fan is to cool the cabinet and the electronics) and stays on until the unit is cool (about an hour after use). The oven is in a new construction 3-shipping container project and the kitchen is in one end of a container and the dining room is the other end. The oven can't stay as is and BlueStar tek support doesn't recommend using fire retardant acoustic foam (which is anyhow toxic) even outside of the encasing 1/2" plywood cabinet. Looking for experiences by others and for suggestions for hi-end ovens that do not have noise issues. Any thoughts?

Viking and American Range have french door doubles. However, you could also consider going with two single ovens instead, this will broaden your brand options.

It took almost a year and three different ovens installed before we got a working oven. No repairmen would work on the oven due to its weight or their lack of knowledge. Within 2 months, I figured out why the lower electric oven was burning everything on the top while the middle was uncooked. No matter which rack I used, cakes or bread or anything burned on the top, but wasn't completely cooked on the inside. Sometimes the bottom was burned too. Emails to A.R. started again, but I gave up after no response. So the electric oven came from the factory unusable in 2013. Now it is 2017, and I am having trouble with the gas oven again. After the oven has ignited and has been on for a while, it starts making huffing or whooshing noises that continue for 5-25 minutes. Sometimes it happens and sometimes it doesn't. I found a video on YouTube with the same issue. From 0:56 to the end of the video really shows the problem. https://www.youtube.com/watch?v=Q4ygoiLDaBI So I obviously gave up trying to get A.R. to fix the electric oven. Now since the gas oven is having problems and the electric oven burns everything because the top element doesn't shut off after it has preheated, I have no working oven. So now, I am back to finding a repairman again. I called A.R. today and they gave me the same companies that could not work on it the last time. I have kept all emails and names so I know who could not work on it the last time. After 4 years, they are doing the same old thing. This is a $7,000.00 lesson to learn. I am curious to know about any other A.R. owners updates. I also would like to know if they have heard the whooshing noises from their gas ovens and how they were fixed (which parts, etc.) and what was done about the electric ovens upper element and how they were fixed.
