I have and like both. The Wuyi bing isn't anything spectacular, but it's a good basic tea. It's mostly thick, sweet, and (lightly) roasty, though it's been a while since I had any.
Hou De's is in a different league all together. It's very complex and smooth when brewed right. I love this one, but with such a small piece I've only dipped into it once. At some point I want to get more so I can have some once in a while
