Sound quality and audio codec compression of these services (Discord, Mumble, Teamspeak, Ventrilo) is generally quite good, they are designed to support rapid coordination of large groups in high intensity situations and e-sports tournaments. It was not uncommon to have 40+ people in a single voice channel for MMO raids 10 years ago, and things have only improved since then. However, your experience will be significantly affected by your choice of headset and microphone. I have spent a lot of time in voice channels and it's common to have long conversations among groups of friends or online acquaintances there.
