I use both and I find Discord to be much better, I don't understand why they don't release a "corporate" paid version that would basically be the current version but with a different skin and without all of the gamer nonsense.

Discord is MUCH better than Slack. But since it's primarily aimed at the gaming community it doesn't get the same audience.

We use Discord instead of Slack for work. It works well, most of the time. But it's not a perfect solution, and some bots / things that are just a few clicks away in Slack we've had to build out manually. That said, prefer it to Slack anyway.

I use Discord in place of Slack for hobby/non-professional projects.

The problem with Discord tbh is I've found it to be less reliable than Slack in terms of uptime/push notifications. It also has fewer devop functions prebuilt which means building them out.

Not a big deal if you are a hobbyist, is a big deal if you are paying people $100+/hr to do it.

Discord feels less polished to me. I find push notifications way less reliable, and often if I do get a notification the app won't refresh for a few minutes to show the message. I think there's no offline handling at all for notifications, so if you're offline when a message it sent you're never notified about it. Search is basically unusable if you want context, they only let you see a few messages after your search term. Also they don't have outgoing webhooks which make bots more awkward.

It is nice that it's free and unlimited of course, it's a no brainer compared to free Slack, but for work I'd prefer to use Slack.

Discord has a huge image problem. I won't touch it with a 10ft stick or even mention it in a professional environment. Besides that it's very annoying that it's a complicated mess that has no real focus.

I've recently made this switch. If just for the sheer performance difference (mostly startup time), Discord is worth it. The free search, file uploads, and audio/video chat really makes it, though.
