Void Linux with musl. I wanted to try setting up a distro with Musl, but many things I use daily simply don't work with it, and the hassle of troubleshooting everything was a bit too much. I went back to Fedora Workstation, and I'll likely stay on it for my workstation (though I'll switch to Fedora Kinoite when Fedora 40 releases). I also use Fedora Server for my personal server, since it's very familiar to me, and there's not a huge point in switching to CentOS anymore with the recent changes, so I'll probably just stick to it.
I'm talking mostly about musl, but Void with glibc still requires more work than a "just works" distro. As such, I didn't see a point in trying Void with glibc, because the biggest benefit I saw to switching was for musl. It's great for some, but not for me, just as I wouldn't use Gentoo. There were a lot of things that didn't run, I don't have a full list. I know for a fact that Steam (or any Steam games) wouldn't run, I'm fairly confident that the OnlyOffice suite wouldn't work, I believe that EasyEffects wouldn't run which was a big problem, since I use that for system wide equalization, and for my microphone filters. I probably could have figured out how to set everything up with bare PipeWire, but it's basically the same story for everything: it just requires way more work. My VPN (Mullvad) isn't compiled for musl, nor was the Nextcloud client, and many things I use every day. Those are just the things I remember having issues with off the top of my head, and it may not have only been musl that was the problem, but it's very likely it was.
