We're big Jitsi users around here. For me the main reason is how WebRTC integrates with my audio visual setup - for teaching music or live jamming there's a good link to my Linux audio environment via Carla and talking to OBS studio. You can get 48KHz almost lossless links over a good connection. That's also great for recording both sides of a podcast interview and stuff like that. Both my partner and I do sensitive work and need good security, so we can spin up our own server and not have to worry about whether Zoom, Google or Microsoft are MITM confidential conversations or selling data that would expose our clients.
