10-Year Gentoo veteran here. Every time I move away from Gentoo I come back purely because I have some headache caused by systemd or pulseaudio (which seems to depend on / be depended on by systemd). If they didn't get in the way I wouldn't care, because not needing to compile packages would be nice.
Recently I purchased some bluetooth headphones, they don't work well without PulseAudio and so far I haven't gotten anything but raw audio files to playback directly.
Same goes for Firefox. I think there's an intermediate plugin to play directly to ALSA, but for now I'm just playing spotify||netflix via chrome.
Point is, it's slowly becoming harder to avoid Systemd and PulseAudio. Because all the major distros use them, the support, development and documentation for !systemd has died off radically :(
