Knowing the path to the log file isn't more complex than knowing the name of the systemd unit, but not needing to know the right set of flags to pass because the sane behavior is the default is _really_ nice. That said, I didn't know about `--boot` or `--since`, so maybe I'll hate journalctl a little less (also, I've only ever used systemd-based systems, so I don't think "it's what you grew up on" applies, at least in my case).
