Counter-anecdote - since switching to operating systems using systemd, I haven’t had a single bug or issue with the init system or writing startup scripts, because finally they use incredibly obvious files that I can write myself.

For me it’s basically magic that I can now write a simple declarative file that describes how to run an application, and from there it works with all of the expected features.

Systemd didn't introduce this, though; many alternative init systems already had declarative configurations.

Yes. However, systemd did this part certainly right --- the service files and their dependencies are much easier to understand compared to e.g. its counterpart in upstart.
