The most valuable feature for me is that it shows who is available and who is not, as well as what their current status is. When I want to check in with someone, I first have a look to see what they're up to and then I can throw in a question or engage in chat with them. The UI is okay and I am quite pleased with it. The options that I have for moving things around the screen during calls are good. It is also modern looking and not clunky at all. The power of the chat function is good in terms of sharing, pasting, and the like, as it is very full-featured. The integration across platforms is really strong. The speed and availability are very good. There is also room for lots of customization built-in, which is a big plus.
