This website seems to describe in detail the advantages and disadvantages of the most popular options in regards of VPNs: https://vpnreport.org/

Seems like the most popular one is Tunnelbear. To be honest, from that list I have already used two: PIA (Private Internet Access) and PureVPN and have nothing against. Stopped using PIA some time ago because there I didn't really trusted their support responses regarding how the logs were being kept or saved.

I have been using PureVPN so far and nothing to complain about.
