The best Payment Gateway for Customer Experience is Stripe as well as Square and Paypal.
Having multiple payment gateways for your customers to pay with can help customers and make them more likely to purchase from you.
Shoppers may abandon their shopping carts on your website if they notice that you don't have a way for them to pay properly and like they should.
Shopify payments are also great for providing a seamless integrated payment and shopping experience and global businesses often prefer Adyen for it's extensive currency as well as region support.
