Have you used both?

Hipchat was basically unusable for me. Constant crashes, sloppy integrations, poor search, and a notification system that did more harm than good.

Slack is completely different. Pre built integrations mean I don't have to spend time writing a bot. Starred search means I can find that message from a few months ago with the click of a button. Auto responses mean I can inject some humor into conversations during the work day. Image comments mean I can use slack to gain feedback on wireframes. I could go on but theses are just some of the things that make slack far better than Hipchat.
