We use Discord exclusively at my day job.

We have a few bots we've integrated with things (deployment, stats, etc).

We use it for all our voice/video calls.

Edit: We've got roles setup well for things like contractors, devs, marketing, etc, so it's easy to lock down different conversations in channels.

It's been fantastic.

The only thing I'm not a huge fan of is the (IMO) poor implementation of threaded discussions.

Edit: it definitely has issues with connectivity from time-to-time too, but not bad overall.

TBH, I'm not sure why companies use Slack (I use it for other organizations, so have experience with it too, but not extensive).
