* No launchd or systemd mess. Runit takes care of the init process.
* xbps: a fast and simple package management software, that also resolves dependencies.
* Clean but scarse documentation, if you have used other distributions you should be fine.
* No automatic configuration of programs, you have to explicitly define what you want for sshd, nginx, etc.
I started GNU/Linux distribution hopping after archlinux's maintainers decided to migrate to systemd, back then I had been using it without problems and for experimentation purposes followed the migration; after a couple of updates I had an unbootable system were systemd wasn't able to run logind, diagnosis showed all files where in place, but run out of time and didn't want to discover what was wrong with it.
I use voidlinux on a T410s mainly for developing, learning programming languages and experiment from time to time with KVM and libvirt (which is another mess), hope to change completely to openbsd in a couple of months.
