Which is better, Qingdao Sanying or Nantong Jianghai Capacitor?

Nantong jianghai is not very clear. Nantong Jianghai is a well-known brand of capacitors in China, and Qingdao Sanying is a well-known brand of South Korea, which belongs to a wholly-owned company of South Korea Sanying. It is currently the fourth in the world. The famous brand used by Qingdao Sanying is also Sanying of South Korea. Last time I visited the factory there, the electrolyte was made by myself, the machine was imported from South Korea, and the quality inspection of the assembly line was strict. Every product has to undergo manual inspection. This is a very good foreign company.
