A few more points:
1. Wx and alipay are still musts now. I agree that it makes sense for union pay to attempt to grab some the gravy, I can't envision them making a sizable dent in the near future
2. CMB and Huaxia both have awesome customer service, which is useful if you frequently receive FX wires, but if you don't, your pain is likely limited to the initial sign up visit only
3. Most of my income is in the form of USD via Schwab. As such, I have a strong preference for banks with CDM machines that are close to my house or office (so I can withdraw from Schwab and deposit to my Chinese bank in less than 2 minutes)
