What client app are you using for Matrix? I really love the idea of switching over to it, or something similar, after Discord's IPO. We tried Revolt, which is now apparently called Stoat Chat, but the 2 killer features with Discord are its screen sharing & noise cancelling. Some of the screen sharing "extras" I could do without, but using Element we found that background noise cancelling is awful. You can hear every seat readjustment, things in other rooms in the person's background, loud breathing, people eating...it's awful.
If not, I'll stick with Matrix. It's got privacy at least as good as signal, with Discord's UX.
