It totally depends on what I want.If I want to access torrent sites, many of which are blocked , or for general web access with more privacy, VPN is used.But when I want to browse censored informations and do or watch some illegal stuff, I use TOR. The thing with TOR is, never login to any regular web accounts you have, as that site will understand you are using TOR and may let surveillance authorities of your country to monitor you.
