There are many factors which you should take into consideration while choosing the best VPN service but looking through many vpn review sites it looks like expressvpn and nordvpn are the best solutions. But I wouldn't trust much to these sites as the ratings is based on the editor's score only, so the owner of the sites may get some compensation for advertising these two. The only site I found more or less "honest" in regarding of the best VPNs is this one https://www.vpnhint.com/best-vpn-services/ the thing is that their overall score depends from combination of editor's and user's score, so looks like the more/less truth. I personally use hidemyass for about 2 years and couldn't face any serious issues.
