Does the job

Delivers what it is supposed to. Would be better if the consumption of RAM and other resources is optimized!

Very useful and painless

Slack serves very well for staying in touch with several teams simultaneously. Support for external links and attachments is good which makes solving complex issues easy. Notifications work very well, if your team knows how to use them. Reviewing the history could be quicker. Now, while scrolling back, you need to wait a second in every couple of days in your conversation history. This is very annoying if you need to look up something from past a few weeks. Search works very well, but not everything is easy to find by text search.

Once you get used to Slack, you don’t think about it much during your work day, which is exactly how it’s supposed to be. Support is very friendly and responsive. I’m personally very basic user and not that interested in most of the advanced features, so i can’t comment on those. For the basic everyday communication it’s very good.
