May be a bias in action. People who like it, or who really don't care much about it (I dislike journalctl, but, apart from that, I'm mostly OK with it) don't waste time writing how not much changed for them and how things continue to work as expected.
This lad seems really enthusiastic about systemd logging and systemctl:

There are a lot of interesting features, but personally I'd prefer to have both binary and text logging. Text logging is in cases where a system goes tits up and you may only have access to some basic tools such as grep, vi etc.
