I see people very often confused about exit nodes, that is the part where most people don't understand the best about Tor. VPN are worse for privacy in every way unless you are running a VPN yourself, which kind of defeats the purpose of anonymity in the first place.
I think it's fair only if you're using VPN from companies. Open source VPN such as OpenVPN not worse than Tor.
But i'm not a big specialist in web safety, so i'm waiting for your response
For privacy purposes it definitely is, for security purposes it is equivalent at best. Tor stand for "The onion router" witch means that your communications are encrypted for every Tor relay along the way in layers, like in an onion. This way no one can know the full path of your connection. There are entry guards that know your IP, but have no idea who you are talking to, there are middle relays who know nothing except to pass along some encrypted data from one relay to the other and then there is an exit node who knows who you are talking to, but not who you are.
In a VPN when you exit a network, there is a node that will connect you with your destination. But it will know who you are and who you are talking to. That means that at least one person knows what you are doing on the Internet. In Tor you don't have that, no one knows the whole story.
As for the security, in theory everything should be equally safe when you are encrypting your communications (using HTTPS for example).
And when you are not, then someone always know your data. Everyone in physical proximity if you are using a local network with a wifi, your LAN, your ISP if you are connecting directly, the exit node in Tor and whoever routes packets for your VPN for the outside of the network. In short, in Tor and in VPN whoever controls the IP the site you are connecting to shows you have is the one that can read your unencrypted network.
