I think Yuxin is giving Moyu some serious competition right now. I wouldn't say Yuxin is destroying Moyu. Moyu is still a solid company as of now and still maintaining its reputation. They should just look out for Yuxin and other brands who are competing with them.
Definitely. Yuxin is making 3x3 and up, while QiYi is making the "side events," like Skewb, Pyraminx, and Square-1. Also, Yuxin and QiYi are both producing amazing puzzles for beginners.
