I want to buy a gold bracelet. Is Zhou Dafu good or Lao Fengxiang? Adding high scores!

I am from Chongqing. I learned that Chow Tai Fook is 330/g, and Lao Fengxiang is 303/g
The people who know what can tell me which are good at the two, and try to talk about it. Including warranty, quality, price, all aspects.
