You can self-host GitLab which may be an advantage for some. If you like the colour purple, there's that too!

You can self-host GitHub as well if I remember if you pay for the licenses. Gitlab does have an open source free version but without all the features.

You can also self-host Github Enterprise I believe.

Self hosted GitHub Enterprise does not allow for public access. So you can't expose your opensource projects to the world using your own instance.

GitHub Enterprise is designed for self-hosting.
