There’s also https://spacebar.chat/, which I’ve been hearing some buzz about, but not really here; not sure if that’s because there are known problems with it or what.
Edit: it looks like voice and video are just experimental right now, so might not be a good replacement for many: https://docs.spacebar.chat/faq/

So might not be ready for primetime. Voice is pretty critical to how I often use Discord. Video less so, but still important.
