I like how quickly you can create meetings. The audio is crisp as is the video, as long as you have solid WIFI.

Ease of setup and ability get up and running quickly.

I think Highfive is pretty easy to use. It's easy to invite others by creating a link or call in #, and adding people onto the call from multiple areas works great. Connection gets a little spotty from time to time which I would love to have go away forever, but does that disappear with any software? I doubt it. I like this program better than others I've tried in the past.
