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.
Yup! That's my kind of approach too. And Void boots just as fast. Up to date, boots very quickly AND is a install what YOU need, without tons of preloaded choices, distro. Arch and Void are at the top of my list for that reason. My personal file server runs Arch, my "client" computers run Void. I was surprised the touchscreen on my laptop (Ideapad 5 Pro, Ryzen 5600U version) worked without any configuration honestly, so hardware support is quite good on Void too.
