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.

Purevpn has been seen as a pretty common vpn service that people use for being safe on the internet. Tunnel bear is okay, but the free version is not something I would use if I was trying to do serious work with a vpn. I'd much rather use something like private internet access, even though it costs a significant amount. They have claimed and have shown that they really keep your browsing and work completely anonymous which is very useful for what you need it for.
