“Puffery”—-wild exaggeration, inflated claims, or outright misrepresentation, usually with respect to advertising. The only place I have heard or seen the word is in legal briefs and courtroom argument, where it is used as an acceptable way (to the judge’s ears, at least) to dismiss or deride the other side’s claims as “ mere puffery”.
I don’t see any of that here, just differing viewpoints on three very nice Swiss villages. I offered mine above. But I want to amend my views on Grindelwald: when I said it is hard to find good views from a balcony in Grindelwald, I was referring only to the hotels along the Main Street, such as Die Spinne, where one is looking up, up, up at a wall of rock, such as the Eiger North Face, but you cannot see the peaks beyond. If you pick a place above town, you can get very nice views across the valley to the peaks beyond and behind that wall of rock.
We had dinner one night outside at Hotel Bodmi, on the Terrassenweg above town. They are situated next to the meadow where the paragliders land, and there was a special area on the deck set aside for the Gleitschirm Piloten. The views from that deck are wonderful. You can get an idea of the views from their website:

And further along, toward Grosse Scheidegg and also above the village, is Hotel Kirchbühl (mentioned above), a place I wanted to stay 20 years ago, but could not afford at that time. Instead, we booked their sister property Alpinhotel Bort, partway up the First lift—-a simpler place with even better views. But in the end, we decided not to stay in Grindelwald that time.

(I might take another look at that place for our next trip—I think the grandchildren would love it).
