We could vote on the two ranges you have listed but your needs might be totally different than my needs. I think it would be better to tell us what kind of cooking you do, what type of cookware do you use and tell us about how you use your oven and why you want an electric oven.

Look up blue chipping in Wolf DF ranges and wall ovens. The Wolf gas range does not have a blue liner so does not have the same issues. There are a few threads on the Miele DF.

Have you considered induction?

Would you consider a rangetop and wall ovens? This lets you pick the best for you of each.

Thanks for the comments. We did consider induction but prefer gas because of our cuisine/cooking habits.
We did consider wall oven but it did not work out because of kitchen layout.
We primarily use oven for roasting egg plant, oven baked fries, etc. We are vegetarian so won’t be doing meats.
In future we may do some baking as well.
I read that electric oven gives more precise temperature control than gas oven so started to look into it.
I see that these some high end gas range provide very high BTU but I don’t think that’s an important factor for us.
