I think the key thing that makes Discord less usable than IRC or Slack for me is how unreads are handled. In both my chosen IRC client and Slack, I can set things so that I am only notified when my name (or chose alias or string) is referenced. In Discord, it's more like a blacklist than a whitelist, and I have to end up muting every channel to avoid the unread counts piling up. Once you mute very nearly every channel and just pop in manually to see what you want, Discord works very well!
