The Advantium won't do that for you either, really. You can warm frozen food on speed cook mode but some of the limits of microwaving apply. The smaller the serving, the better it works. Family sized portions take longer, and you have to work harder to make sure the interior is fully and evenly cooked. There is a loss in quality when you take short cuts. Some people can use a speed oven to cook many things as well as they could in a standard oven, in about half the time. That's cooked from raw. With anything frozen, especially if it's large and dense, you'll have a much better result if you thaw it first. From there, speed cooking could cut the time for warming. And the Advantium isn't bad at defrosting.

I have both a Gaggenau combi-steam and an Advantium, but I don't have the time pressures most of the time to need to speed cook. If I had to choose one, I'd choose the combi- and a basic model microwave, because there are things that I like to microwave. You could probably do all of them in the combi-steam though.

Part of the reason I have an Advantium is for the third oven space it gives as a convection oven. And I thought I'd use the speed feature more. Gary (Dodge) has posted a lot in the Appliances forum about things he makes in his Elux speed oven. Do a search for his posts to learn more.

I believe the Miele Speed Oven would be more like the Advantium.
