UNIX sockets (as opposed to TCP sockets) are faster and more efficient, and less prone to accidental disclosure to places you don’t want connections coming from. A misconfiguration can potentially cause a listening TCP socket to be exposed to the Internet, whereas there’s absolutely no way you can make a mistake such that a UNIX socket is exposed directly to the Internet.
