How does Alipay's user experience compare to Paypal's? Is it the lack of competition that has enabled them to expand their reach so widely (by not having to focus so much effort on each venture)? For example, the experience of shopping on AliExpress is (imo) sub-par when compared to most Western online shopping experiences I've had (Amazon, Zappos, and even smaller retailers).
I don't know a whole ton about the Eastern market to be honest, so I'm open to being educated.
