Which downdraft vent? For a new kitchen? Who can recommend something?

And, a modified kitchen layout still allows for a ceiling extractor hood, a nice wall-mounted extractor hood, etc.

Someone here once recommended the Oranier KFL 2094. It comes in both the recirculation and exhaust versions. The price at 2k€ is also correct. Check it out on YouTube. We ordered exactly that one with the kitchen.

Are you satisfied with the unit?:::was recommended to us by a kitchen studio as an alternative, also price-wise, to Miele / Bora

No idea. It's ordered and will be installed. I only know the videos on YouTube.

Alright. I thought it was already in for you... but you're just getting started

I recently had Miele demonstrated to me, and I have already tried Bora professional myself.
I wouldn't like Bora Basic; it takes up too much space in my opinion, but I have to admit that I lack experience with it.
Bora professional was great!
The argument: "if something boils over, you never get it out again, and it's so complicated to take apart the device" I cannot understand either for Miele or Bora.
Both fans can be disassembled with a few simple steps and then the parts go straight into the dishwasher, the compartment is made of stainless steel and can be easily and effortlessly wiped clean.

What I don't like about Miele is, for example, that there is a groove around the Tepan field (I personally imagine this to be annoying to clean; but as I said, I haven't been able to test it myself yet).
Overall, I prefer the Bora concept, but that is certainly a matter of taste.
That's why we will have a bora professional with induction cooktops on one side and Tepanaki on the other.
I also didn't like the Miele induction cooktop as much as the one from Bora. Miele has the usual round heating fields, while Bora, as is common in gastronomy, has the induction field over the entire surface. So two rectangular fields that can be controlled separately, which can also be used together if, for example, you want to heat a large roasting pan over both fields.

However, I am convinced that you can't go wrong with either.
