If production is servers, then alpine is the better choice as it provides stable releases. Void Linux is a nice desktop system and you can run it on single servers you personally take care of. But I would rather not use it at scale for servers as updating rolling release can always lead to issues and not updating will leave security issues unfixed.

The one benefit would probably providing a glibc version if you require it.

Void is rolling release; I would prefer Alpine for production environments. Void is an amazing desktop, though.

I always considered Alpine to be that slim OS image that is used as Docker containers. I have never considered it as a serious bare-metal host. May be it is indeed better than void for that purpose.

I wrote about void because it “felt” like the philosophy of BSDs in the Linux land. Which is quite a draw for me. Binary packages, up-to-date kernel, and a sane init system felt fresh and in KiSS realm.
