Tor, although free and decentralized, is not designed for the same usage. It provides better anonymity than a VPN, at the cost of much reduced performances and in some cases security.
While communications are very secure between two tor nodes, to communicate to the existing web ("clearnet") it needs exit nodes that will see and handle all your traffic, and some of those have been seen to abuse that trust. Our servers don't do that.
A VPN can be used for everyday browsing, online gaming, and you can pick a server close to you for best performances.
For anonymity, tor can be used over the VPN to hide your tor usage to your ISP or school, as it could be used against you.
