With these systemd mount files I don't need to touch the fstab, I can use ansible to copy the file, enable the service then start it. I can also have other services like Docker, Jellyfin or whatever to depend on that service. If the nfs share can't be mounted then systemd won't try to start docker.

So you can easily start and stop it as a service and you get your logging easily accessible via journalctl as a unit. But practically speaking there's not much difference.
