I've been running void-musl on my own notebook as well. My needs are most likely different from yours as I only use this while travelling, and all I do on this box is connecting over ssh/serial to equipments, and read docs/emails on the internet.

For this purpose, it works quite well. I had troubles getting surf-webkit2 to work correctly, but firefox works like a charm (putting aside the fact I have only 1g RAM...)
Using runit gave me some frustration moment though, as it's quite different from the others init systems I know, but once you get used to it, eveyrthing just works.

Having tried to build up a musl-only distro, I feel your frustration though, and can confirm that many software are not ready to support it. I was prepared to that though, and was suprised by the amount of software working with musl! I didn't expect there would be that much!
I also use alpine on my servers, and I've yet to find a software that doesn't work with musl, or doesn't have a working musl equivalent!

Also, welcome on the linux boat jkl :P
