Do a search at the bottom of the page regarding these two ranges. You will have hours of reading. I did and I ordered the Wolf 36" D/F last week. I found that pretty much NO ONE had really anything bad to say about the WOLF.
If you read the search you will be able to make up your own mind

Hi cjays.
I have the Wolf 36"df and it's a very good unit. The convection oven is a real plus. I never had convection and worried I would have to be retrained but the conversion was very easy for me. Great roasted chickens. Three racks of cookies at a time. Pizza and calzones on the bakestone are great. Pork tenderloin with the probe, braised roasts...well you get the idea. I'm a fan.

If you h ave the money, get the Wolf.

I, too, have the 36" Wolf DF and I LOVE it!!

We went with the Dacor 36" DF. Liked the performance and looks. My wife liked that it wasn't too pro looking.

We went with the Electrolux 48" (made by Dacor). I preferred it to the Dacor in that it only has knobs, no electronic front panel. Just like the traditional looks, I guess.

Here's a picture:

It isn't installed yet (renovation completion is probably 3 months out), but it sure looks nice sitting out in the garage. We've unboxed it, and it feels great... solid doors, heavy grates, just a nice unit. We got a great deal from Allstate Appliances in Pheonix, AZ... they shipped to us (AL).

Looking inside, and comparing it to the Dacor 48" range, it is obvious that they share many, many components.

That said, if money was no object, the Wolf would probably have been my choice. I've never heard much negative on their ranges, and they are gorgeous.
