Because of the ubiquity, nay, monopoly of systemd I always assumed it was miles ahead of other init systems. Nope. I've been using a non-systemd environment for a while and must say I'm surprised by how little breaks, i.e., next to nothing. Moreover, boot and shutdown times are faster. I'd suggest trying it out.

Sure but performance tweaking is a different argument than "init is better because it is fast". If you watch the video link I posted it explains why systemd exists and its benefits. Speed alone isn't a good metric for an OS
