According to r/VPNTorrents, Proton and AirVPN are the only recommended VPNs since they are the only well-established privacy-respecting ones left. New ones are popping up with promise, like Azire, but time will tell. As for Proton, I decided against it because of limited port forwarding and lack of IPv6 compatibility and settled on AirVPN. Also, I personally try to avoid keeping all my eggs in a single corporation's basket, so I cannot advise buying into the full Proton suite if you're remotely tech savvy and/or privacy-concerned. But they are genuinely great products if you have no desire to do any tinkering or shopping around. I just can't see the appeal in my VPN activities being directly tied to my email. Oh and I almost forgot, I switched from PIA due to their lack of IPv6 support and acquistion by Kape, a known adware company.
