Continuous GratesAll of them have some version of continuous grates, some more appealing than others; becomes personal preference. One of the things that bothered me - then appealed during my "extgended indecision" was that some manufacturers had different size grates... for example, if looking at a six-burner (36 inch) model, some had all six burners the same size, some had the center two wider (at the expense of the sides) to accomodate oversize stockpots or pasta pots. Finally, all I asked was that the grate accomodate a 12 inch pan/pot.
I did a lot of research on the net. Every manufacturer has extensive pictures and details available. After lots of web-looking and taking of notes then I went to visit retailers.
My Wolf is here but is two weeks away from installation. This remodel is a total gut of a thirty year-old house. The electrician is still going nuts. Cabinetry should start going in next week with the appliances to follow.
And, to answer your question, the Wolf oven cavity is the largest in the 36 inch frame. How they do it I'm not sure but a friend warned me how shocked she was to discover her Viking oven was too small to hold her roasting pan except on a diagonal.
On asking, salesman started talking about interior space of all ovens. Dacor is another excellent manufacturer; several thousand less expensive than Wolf.
Wolf, by the way (in case you do not know) is now a wholely-owned subsidiary of Sub-Zero. I do not know how the product has changed but the "marketing" has improved considerably.
