It’s basically like… this nice compromise between Arch and Gentoo. You got precompiled packages, but if you’d like, you can compile everything from source. xbps-src is like Portage on Gentoo, except some of the more popular packages get precompiled and put on the main repo (kernels, libraries, office suits, browsers, etc.).

I like it cuz if you’d like, you can get nitty gritty about it, but if you’d just like things to work out if the box, just use the repos and off you go. Plus, it comes with xfce by default (if you choose the DE ISO), which is what I use, so saves me the time to set up xfce. And it has a non-free repo, so that’s also a big plus (take a proprietery package, repackage it for Void if the license allows it, if not, just leave the template in xbps-src and let users make their own package).

Also, it’s incledibly stable for a rolling release distro. I also use it on some severs, I’ve never had a single one break something after an update. It’s not as bleeding edge as Arch, so they’d rather opt for not something as new, but more stable, which I also like.
