Alpine is extremely popular for containers due to always picking lightweight choices like not using systemd. I don't think any of the Google distros (Android, Chrome OS) use it either but that shouldn't be particularly surprising. And of course hardcore classic Gentoo still lets you pick whether you want to or not. Void for a more traditional "user desktop" distro.
I like systemd and those are the only cases I remember being surprised the usual commands didn't work.
