It's not so much superior as the computers that people tend to use have become inferior in networking capabilities (smart phones, can't hold open tcp connection, random round trip time back-off, no actual routable ipv4) and the people tend to know less about how to use the internet (don't know how to upload images or use URIs, etc). Discord is a superior chat mechanism for modern smartphone internet users in the same way that using crutches is a superior walking method for people with a broken leg.
