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.

I agree with you entirely, And I also use Purepro, great if you want to hide your IP. But still a lot of other VPN software as well as Zenmate, HMA Pro, CyberGhost VPN .... you can experience it. Purevpn software, when we choose a country to connect to, can see that there are many IP addresses in each country.

You seems little bit Sounds with the IT knowledge. Please be sure that you should dig up the old topic which is been already answered and op satisfied about his query. By the way you can should not dig it unwantedly. To be go with official VPN client contact you can use Cisco client to that.
