I use Void Linux. I like how much more up to date the libraries and apllications tend to be, it's quite similar to Arch in that regard, as it's a true rolling release just like Arch.

It also tends to be very stable as well, with couple minor issues I had ever experienced got fixes within 48-ish hours. One was hugin not launching, and the other a transition issue between pipewire-media-session and wireplumber being the default.

Void uses runit for service management, and is still multithreaded despite taking a more similar approach to just plain shell scripts, and constantly monitors services. What I like about this is more much simpler services are to write compared to SystemD, and then you just put a simlink to them from /etc/sv/ to /etc/runit/runsvdir/default/ to enable or disable.

Void also uses their own XBPS package system, which operates similar to pacman, and is equally fast. Void is basically a rolling release like Arch, with the latest updates, but instead has a more "classic" system management style, which I for one greatly appreciate.

After nearly a decade of distro hopping, Void is where I landed for at least the past several years, and I see no reason to leave. Just sharing incase someone else out there thinks this sounds like the system for them, and if so, Take a Step Into the Void, it might be what you're looking for. That's what I like about there being so many distros, there's choice to match each one's needs.
