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.

I'm not sure what this website is adding here.
It looks like it and all of the linked websites were created in 2015-2017 and never updated.
Look at the "Notable bugs and security issues" list. It's a bunch of things from 2015-2017 which are resolved/closed/merged PRs.
Or linked websites which consists of such well though out pages as: "Things that are good about Systemd - It starts services ig" & "Things that are bad about Systemd - *everything*"
I can't imagine how much information or insight there is to be gained from a website that is out of date by over a decade.
