Yes, Astrill and Express VPN has been popular in China. But probably because they are too well-known, their services are not totally reliable. Instead, some smaller VPN providers now offer better services. Check out this test result: http://www.vpndada.com/best-vpns-for-china/
I visited your page expecting to see details of a testing methodology, along with results for a number of providers. However, the information you provide is no better than that provided by friends' anecdotes.
"Reason for Recommending: Reliable connection, fast speed. Fast customer support."
What do you mean by 'reliable'? What do you mean by 'fast'? Are you talking about latency or throughput?
"Reason for not recommending: sometimes hard to connect"
How many times out of ten? Using which VPN protocol(s)? Was this using PPTP, or OpenVPN over stunnel?
I run my own VPN servers (for myself and friends) but of course there is some ongoing maintenance effort to add new servers to replace those for which latency and/or throughput have declined. If there were a site with specific data about different companies' performance (over time), that would help me to decide whether it's still worth the effort.
