Great info of these 2 major payment gateway.
I am a royal Alipay user for years and I like their services, but lately I realized that they try to push their Apps, such as for free transaction or so, but one thing is let me down quite a bit is that when transferring a payment if the internet connection is bad, your payment either not send or they took the money from your bank card but failed to submit to the next bank and the system will send the money back, which is hassle sometimes.
