Alpine is musl only; Void has both glibc and musl variants. Void seems more desktop-focussed than Alpine, and (at least as of a year ago) I didn't have a lot of luck with ZFS on Alpine.
Hehehe I wrote the original wiki entry (because someone on irc asked for something like that)
I think it's still the recommended way for dependency management reasons and missing glibc-packages. If you can get your program running with the alpine glibc you should probably do that
