2018 update on-topic:

I (yes, I) have spent the past three months with Void-musl and I can't really recommend it. Not because Void would suck - no, Void is actually lovely which frightens me since it partially destroys my hatred towards Linux. It is the musl library itself which has adaption issues: Most things work flawlessly, but most large packages (including Chromium and its descendants, e.g. qutebrowser) refuse to work on the musl spin. Other software (like Android Studio) which is partially "closed" is not even available on this version.

For hardware reasons, I still can't switch to BSD yet, but I'll need to replace this Void soon. Since my experiences with musl were not quite good, I should probably reevaluate my options - one of Void's killer features is out for me.
