best vpn to use?

I think to better answer this question, it depends on what your needs are. If you're looking for something that'll unlock region locked shows/episodes on Netflix and have minimal security needs, then you can probably go for something like NordVPN or even Private Internet Access. I'm personally weary of any VPNs that are owned by US companies just because there's still a lot the government can demand from these companies that may compromise your anonymous identity on the internet.

I've used PIA in the past and it has gotten the job done in terms of being able to securely complete "certain" tasks online, but I've since moved onto a different VPN provided that is slightly more secure based on research.
