Certainly possible to be better than Discord. I tried Discord once for a friend’s virtual party. Horrible sound quality, horrible connection issues both on Windows client and iOS app - not to speak of fully pegging the CPUs for a video chat app. The experience was far worse than a Zoom or Teams call.
Maybe for 24/7 gamers who have tweaked it until they found the right setup, Discord “just works”, but for me it seemed unfit for purpose.
