The issue I've found with the PC setup, which I've been using after being somewhat unconvinced by Volumio, is that for dynamic playlists, the clients don't seem to agree on the contents. I have to manually go load the playlist on the player PC so that when the songs advance I can see it on my local computer. The player PC only does that, so I never interact with it.
