I've seen very nice collectibles offered on Bitcointalk over the years, some for free and some were offered to me. It hurts having to reject them, but I'll always choose privacy over material goods.
I myself visit the collectibles board sometimes but even if I want to take something from there, I can't take those for privacy, because in my region cryptocurrency and everything related to it is illegal.
And I think that since it's a Bitcointalk Community Award, there are a lot of people in this community who have the same limitations as me, so I also think that giving money or bitcoins as a prize would be better than hardware wallets.
