Just learned about it recently. It has received a lot of praise as a rolling release distro. Also it uses runit instead of systemd.
It has been praised also for being more stable and better designed than Arch.
And I wonder how it compares to OpenSUSE Tumbleweed,
I use it as a desktop. I like that it’s free of the nasty surprises of modern Linux (flatpak/snaps, systemd, X11 is still pretty first-class) while not feeling quite as isolated as Slackware and its sort of pre-broadband approach to packaging.
My biggest issue was poor support for an old Epson scanner that rewuired a binary package that wouldn’t install cleanly as it was designed for Debian; solved by buying a $10 used Canon scsnner which worked out of the box.
I like it better than Devuan for a non-systemd distribuition because, as its own thing, you don’t end up with as many “do I need to follow the Standard Debian guides or do something special” questions.
It looks like a pretty solid distro. But yeah, you need to know what you’re doing. I think if you put in the work it can really pay off.
