Easier to use than WebEx
We switched from Cisco WebEx to RingCentral early this year, and so far I've really enjoyed my experience. I found WebEx to be quite outdated in it's functionality and design, RingCentral is much easier/simpler to use.
While I have not experienced this, a few of my colleagues have complained about audio outages and connectivity issues. It seems there are still some kinks to be worked out in the platform, but nonetheless, I'd still recommend the tool.
