Hipchat is a piece of shit. Inline code highlighting anyone? /code is crap.

Slack has more speed, better integrations, better search, reliability. (For example, getting notifications on iOS.

I hate HipChat. Apologies to those that love it, but it's likely you never used both side-by-side during normal working days to compare.

So if Atlassian tried to put their mark on Trello, I have little confidence that it will still be Trello.

I used HipChat for two and a half years in a previous role, and have been using Slack daily for the past 7 months in my current role. Both are fine.

HipChat is certainly not perfect, but I don't agree about Slack being faster. It definitely has its issues.
