In my last job we used Skype for Business. Worked decently once we got connected. But invariably it would take 10 minutes for everyone to actually get connected with working audio. And actually we typically only used audio, so didn't even have to worry about video troubles. Still it suffered from people entering "presentation mode". Agreed on Hangouts.
