Almost any distro is fine, you just need to know how it works and what to change to make it good for audio. If you need a daw and vst/lv2 plugins then the package managers can become important and whether you want/can spend time/cpu compiling.
I would say if you are inclined to delve into linux then gentoo/funtoo is the way to go (personally I don’t see the point in arch when you can use gentoo, it’s convenient but the difference is like arch to ubuntu), and if not then whatever suits you needs. Debian/ubuntu based is always handy for the kxstudio repo.
