I have the HuangLong, though not the WuJi, so I can only speak from experience for one, but...Give a old man some advice ....
Time to get a new 7x7, just can't decide which one, The YuXin HuangLong or the QiYi WuJi.
Currently got a cubic AoFu.
The HuangLong is apparently slightly larger than the WuJi by a number of direct comparisons (even though it's listed otherwise), but it's still a good size. The stickerless tiles do have a tendency to fall out, but once you replace the offending tiles with the spares it comes with the issue will mostly disappear. The WuJi comes in stickered, and its pieces are the normal split design, so it doesn't have that problem.
I had to go through a lot of trouble to get rid of spring noise in the HuangLong, but now that that's gone it's one of the smoothest puzzles I own. I've heard it described as 'two flat surfaces rubbing against each other', and that's pretty much accurate. The WuJi has more feedback, it's lighter, and if the rest of the Wu line is anything to go by it has a more pronounced speed gradient across the layers, and has more of a swishy feeling.
I personally prefer the flat and smooth feeling for cubes larger than 4x4, so I got the YuXin and am very happy with it.
