Well, yes, TOR is also an option. And it does have the benefit of being free. But in my experience, it's much slower. You also end up with a somewhat random final TOR node that could be in any state or any country, which can cause websites to serve you a page in languages you don't understand ... or, sometimes, refuse to load at all. For example, if your exit node is in a US state with a porn ban, some porn sites will refuse to load anything useful for you. Sometimes there's workarounds for that part, but it's always quite slow. Maybe okay for images if you've got patience, but trying to download or stream videos (or gifs) through TOR is pretty painful in my experience.

With a (good) VPN, you can be protected from ISP spying while still having good, usable internet speed, where things like streaming videos are still practical. And you can (usually) choose where you want your VPN server to be located, so you can avoid those pesky geo-locking issues.
