Other than using iPlayer, another use for me is to access the Internet while I travel to China.
From what are suggested here, and from Internet reviews, I think the big and good ones are: Nordvpn, Express vpn, and PIA. Mullvad seems to be excellent too, but I think it is a smaller company. Nordvpn was hacked awhile ago. and PIA will soon be acquired by Kape Technology.
If Nordvpn has not been hacked, it seems to be a clear choice. There are many happy customers too.
Maybe it comes down to Express vpn vs Mullvad.
Express is rated best for China here: https://www.techradar.com/uk/news/best-vpn-for-china-our-5-top-choices
I note that it may be illegal to use a VPN to circumvent the Great Firewall of China, so you might want to look into that before committing to using one there.
BTW, My understanding is that Nord had one server, out of tens of thousands, hacked via an out of band management port and that the only people that could have been impacted were those connecting through this server in Finland. I think the press reporting of this has, in many cases, overstated the risk. Nord were certainly not the first VPN provider to be hacked and they are not the last one either. I have no intention of changing to another provider before my contract expires.
Note: I'm not a security professional, but I do design infrastructure for a multinational financial institution and I have had some security training and experience (e.g. Certified Penetration Test Specialist AKA Ethical Hacking). YMMV.
