I you really liked the Zhanchi then I'd go with the Weilong v2 hands down.
There is no "good cube for my speed" you can always adapt the cube a bit and make it slower or faster with lube. I'd chose the cube that has the feeling that you like the most and feel comfortable with so, judging for your preference for the Zhanchi that's my recommendation. But take into account also that, of those 4, the Hualong is the only one I have not tried, so I'm basing my advice on what others say about this cube. Other good and cheap cubes with somewhat similar blocky feel are the YJ ones, specially the Chilong (it is my main).
I really hate the Yuxin, for me it does not feel at all like the Aolong. Perhaps I have not set it right or have not tried it enough but it feels bumpy/bouncy, perhaps it's because of the springs, not sure, but for me it's like a horse that doesn't want to obey, when you try to force it a bit, bacause of inaccurate turning it jumps at me and turns whichever way it wants. Any tips?
