The latency thing drives me nut as well. It depends a lot on the provider though.
Microsoft Teams is the worst in my experience (though it has gotten better), with 1 full second of RTT not even being out of the norm.
Discord though? It’s great. They built it for gamers, who need to be able to give information quickly, and it shows. At work everybody is accidentally talking over everybody in Teams due to the latency, then you get in a discord call and it’s like you’re in the same room. Insane that latency does not factor much or at all in Microsoft’s KPIs.
