This is just the latest case of a Chinese company copying a Western technology and making it categorically better (other examples include weibo v. Twitter, Qunar v. Kayak, QQ v. MSN, and Dianping v. Groupon).

I particularly like the feature that allows you to switch between your phone and your computer using the QR code (first time I've ever seen a good use for QR codes), though I must admit that offering a PC based client would address the same problem.
