I didn't check out the Thermador but I did look at the Liebherr. The Liebherr looked very nice but I wound up getting a floor model SubZero for less and I think it was a nicer fridge than the Liebherr.

I had the same choice a few months ago as part of a new construction. Chose the Thermador. It appeared much better made, brighter and I liked the layout/ergonomics better. Also, much better local service where I am. It was quite a bit more money than the Liebherr (new vs. new), but it seemed worth it. Couldn't see the benefit of spending more for the comparable SZ. We'll see, getting it next month.

I'd get the Thermador - wish I could have found that deal.
