I'll start then...
I used to own this one...
... and was very happy with it for a while. I particularly liked the bracelet - unrivalled at the price point and just lovely.
I ended up selling it for a couple of reasons: I had (and still have) a Stowa Flieger which in my view trumps the SBIII in terms of dial design. It also ran about 20 seconds fast a day - something that, had I loved it enough, I could have had regulated. But I didn't so I didn't and I ended up selling it.
No experience of the Damasko or Sinn, I'm afraid. Isn't a DC36 a Dyson? :lol:
