This relies on properly configuring all relevant software to use the SSH tunnel as a proxy. That's very difficult to do in a way that you don't end up leaking information over the real connection.
OpenVPN works on a lower level and just tells the operating system to use it as a gateway (as configured here) and every software will magically start routing traffic over it. This is generally what you want for security, but can be annoying for bandwidth or latency sensitive applications.
