/lib and /usr/lib are the same thing, or will be the same thing in a
future release. Don't worry about that.
/run is transient. It's an in-memory file system, created and populated
at boot time, or by running programs. It's not a place for configuration.
So really you're looking at /etc vs. /usr/lib.
/usr/lib contains the defaults created by the Debian maintainers or the
upstream authors. When you install a new package that has a systemd
unit file, that's where it'll go.
/etc contains the overrides and configuration elements that are unique
to your system. If a service is masked or disabled, it'll be done here.
If you install a locally built service, and write a systemd unit for it,
this is where you'll put it. If you override part or all of a package's
unit file, you do it here.
