systemd is insecure, bloated, etc

[Citation needed]

If a distro that doesn’t use systemd ends up booting much faster or being much easier to configure, maybe those are features you care about. But switching away from systemd in this case is merely an implementation detail. What you’re really doing is moving from a distro to another one that serves you better.

Otherwise, the choice of init system has very little impact to the average user. Maybe it’s worth it to switch init systems if you hate the syntax of unit files and/or the interface of systemctl/journalctl and you use them often enough to warrant the effort. The people who want to use alternatives to systemd without having such a practical issue with it are doing so for philosophical reasons.
