I have to obviously say that I would own a niffler simply because that is my nickname now. My niffler could find me all sorts of shiny things, but I would have to train it to not steal those things. That would be bad.
I also may like to own a demiguise simply because Dougal was adorable in the movie, and I kind of fell in love with him.
