I use AirVPN, which is like six bucks a month, and sometimes TOR. I use them as network and web dev tools, so I don't mind saying what I use, but most dudes won't tell you which VPN they use. If you need to be able to send all traffic over encryption or manually route packets through certain regions, like to test DNS resolution from another location use a VPN. If you just want a little more security from *insert tin foil* of want to make purchases with a little more safety, just use TOR. TOR has more stable speeds in my experience. If you need security, use both, safe habits, and a secure OS.
