Discord wins in a lot of ways. A few that jump out to me as important are :
* Cross-Platform - You can reliably stay up-to-date on discord from basically every device you own with reliable notifications
* Excellent group voice chat quality and controls - Every user can control the volume for each chat participant(You control your own mix.) This is something Teams doesn't have and god I wish it did...
* It's Slack for friends. Discord basically does everything Slack does (rich-media real time chat with a specific group of contacts.) It's far easier to crank out a new discord for your friends and you don't get slammed with the "Free Organization" restrictions that come with Slack.
There are lots of things it does right, but these were major selling points for me.
