We initially used Skype on our team to communicate with others. However, the software was horribly buggy on OSX. Slack has become part of our main toolchain. It works, has the basic features you need and doesn't get in our way. The integrations are great and we'll continue to use them.
Unless Microsoft rebuilds Skype for the ground up, I don't see us leaving Slack for it. They had their chance, and they dropped the ball.
