I can't quantify it but having tried a few different Rpi wireless streaming options, Volumio has been the least successful at being there when I want it, especially via Spotify.
In terms of similar offerings, Moode has been much better though the interface is a little less user friendly.
RopieeeXL has easily felt the most stable but requires BubbleUPnP for streaming from a local source (fine by me).
I've got 4 rPi's 2 just screens, 2 endpoints for Roon. All running Roipeee and the whole thing has been pretty dreamy.
