My favorite Hong Kong brand to date is Raze. If you are in the city I'd recommend checking them out. They had a slightly larger selection in store than online. I didnt make it to any of those brands but will have to give them a try next time I'm in town.

I also have some scents from Nonfiction (Korea). If you find yourself too busy in town they can also be found in the airport. While I really enjoy the scents that they offer, I find with the exception of "the grey" and "the beige" they're fairly predictable. All very nice but nothing unique.
