Which is better, sab zipper or ykk?

YKK (Yoshida Zipper) is the originator of the zipper industry, representing the industry standard, and its price is about 10 times that of other brands of zippers. YKK is the largest market share owner in zipper industry. SAB (Wei Xing Zipper), as the first listed company in the button and zipper industry in China (stock abbreviation: Wei Xing, stock code: 002003), is well-known in China, but there is still a big gap compared with YKK. So YKK zipper is better than SAB zipper, but there are many fake YKK zippers in the market, and there are almost no fake SAB zippers.
