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,
You will certainly get glowing reviews from its users.
As someone who never used it I have the impression that it is quite good. With a similar approach as ArchLinux, but without systemd. So if the latter is important to you, you’re probably better off with Void.
Its main features look very similar to ArchLinux to me, e.g. the “hybrid” package management.
But I don’t know how much of a niche distro Void is - it certainly used to be - and I’m generally not a friend of niche distros. That’s nothing against Void per se.
