Better? Sure, for you maybe.

Overwhelmingly the word I'd use to describe Discord's interface is "one". There is one interface. It's an interface that most people seem to like, but we've lost an important freedom there. It's against the EULA to modify your client or use an alternative one.

If with IRC one can have any interface, I would not call Discord's better.

Maybe it changed, but how do you share a screenshot on IRC?

Use Pidgin or The Lounge and do it like normal.

Whether we should be using text chat clients as FTP clients is another issue, XMPP is better for multimedia messaging.

Some modern clients (or clients-as-services) build in image/file sharing.

And no netsplits/nickserv insanity.

Or people purchasing a holding company and proceeding to take over the entire volunteer ran network a few years later. :)

Luckily since there is no expectation of an archive, migration is fairly straightforward if there is an alternative. If there are no alternatives, I guess they can try IRC ;)
