Whether it is better to use credit card or Alipay for online payment is considered from the perspectives of convenience and security.
Very convenient. From the security point of view, it is recommended to use Alipay, because Alipay is a third-party trading platform. Money can't reach the seller until you receive something. If there is a problem, you can also apply for a refund. Alipay will not casually put your money into the seller's account. Online banking directly transfers your money to the seller's account (before you confiscate the goods, of course).
