I regularly take part in programming groups, paper reading groups, and book reading groups with Discord. It works flawlessly without any problem. Screen-sharing, video chat, voice all work properly as expected. I also admin several servers, some of which are completely unrelated to tech and non-tech people find it seamless to use. And their noise suppression just works. I have only seen better video quality in Google Duo, and better voice quality in 4G VoLTE calls. Only three issues I have with Discord- 1. It requires high speed internet connection. How high? People with 3 MBPS reported seamless use. 2. The clients are resource hogs. The mobile clients drop the battery too quick, and takes too much RAM in PCs. Although the latter has improved with updates. 3. I am concerned about privacy. Discord is as close-sourced as it gets.
