In the end I choose to pay for AJS 爱加速 for my Chinese Entertainment use case, RMB198 for one year.
I chose AJS because I used it when it was free, the number of servers were impressive, the speed was not bad either with the right servers.
I have paid VIP for Youku Video, QQ Music and Xiami Music, all three apps mostly work without VPN but some contents still require China VPN. AJS works fine for them.
I also tested Tencent Video and iQiyi, both work as well. But now lots of contents require paid VIP membership. And ads can be long without VIP. So if you are interested in the contents (both are better than Youku Video), it is better you pay the VIP.
