re Discord, the funny thing is that Discord is proprietary, and I'm not sure how exportable any data and/or voice/embeds are when you want to download it out of the service itself.
Also can't script the client, you can't run your own server. Also with MIRC IIRC correctly you could layout the chat windows pretty much anyway you wanted and even have like a desktop background.
Discord is a lot easier to use, but in a lot of ways it is really limited compared to the IRC clients.
