Some of WeChat's real pain points are: - No backing up your messages to the cloud like WhatsApp or having them loaded from the server like Facebook Messenger. Moving all your messages from one phone to another is quite the ordeal .
- Complete disregard for platform standards. Specifically notifications on Android and Windows 10 are atrocious. Both WhatsApp and Facebook Messenger have notifications that are well integrated with the especially the Android notification system, WeChat notifications however are not.
-A lot of nice to have chat features are either non existent or have just recently been introduced. For example a poor implementation of quoting a previous message was just introduced like a month ago, and there are no reactions for specific messages -- and no timeline for implementing them either.
WeChat does have quite a bit of different "apps" built into it, but not really more convenient to use than the separate apps are. It's mainly just a casualty of China's lack of anti monopoly legislation.On my phone I have Alipay (the other half of china's online payment duopoly) installed together with WeChat, and almost always use it for payment (It's pretty much accepted everywhere WeChat is)
