Sorry Teamspeak, but you lost me already. Back about 7 years ago when I spent more time online with friends in school, we tried to use Teamspeak multiple times, but the audio quality was always awful. We didn't like Skype either, but the audio was still better, so we dealt with the bloat. Discord is king in my mind, without question. Being electron based makes it a bit heavy, but I can spare 200MB on my machine for some damn good chat and call.
