Yes 12VPN is also recommended by the author of tipsforchina.com for China GFW bypass. But his comments say that 12VPN is more targeting mainland China users and not that good for privacy due to the lack of no log policy.
Astrill used to rank very high in the list of VPN vendors. Once upon a time it was also the No 1 choices for unblock China GFW but then was heavily targeted by Chinese Authority and then not working any more. Now it disappeared from the list of top VPNs from various websites.
You rely too much on the blogs and what those websites recommend, I don't. I rely on my personal and others experience directly with the mentioned VPNs. Just think twice why you think those websites rank some VPNs higher than the others? And this guy from tipsofchina, which I admit has a useful blog (if you know how to read these blogs...), his rank could easily change daily depending if the authorities decided to "switch off" the lights or not.
Your list of 14 VPNs is pointless, "worth looking at". These are not girls we are talking about here but personal experiences with VPNs users have. You have to stop blindly following VPN ranking websites, as in majority they know nothing, apart from how to earn affiliate commission.
Speaking of which, if you would dig a bit, you would know why Astrill has disappeared from the blogs and ranking websites. But yes, you won't find this information there I am afraid. They had affiliate program before which they have decided to stop at one point. Angry "commissioners" (read: VPN blogs) have decided to take them off, because no money no honey. It could be that Astrill, after revamping their website, has brought back the affiliate plan in place but the trust has already been damaged. If you dig even deeper you will learn that people in China are still saying that nothing works better than Astrill.
Any gd vpn for nVidia Shield TV?
Astrill. Reason is because they have OpenWeb protocol on their AndroidTV, which won't slow down the CPU like traditional OpenVPN offered by majority of VPNs. Alternatively a provider with SS proxy (like 12 VPN) and official SS Android client.
