For me MS Teams has been the most reliable experience after plain-old IRC but with the added video/audio/screen sharing features. The only bad experiences have come from somebody using a terrible wireless link, nasty Bluetooth devices, or just using the laptop audio devices in a noisy environment. This is our corporate ms teams so maybe we get allocated our own compute and bandwidth resources though.
Edit: now that I think of it, the key-press to light latency is horrible on macOS. Even worse than in IDEA. With sometimes just stalls after which the whole paragraph I typed pops up.
The latter issue for me is always caused by having one too many browser + CEF/Electron app open at the same time. Killing one of those usually fixes it.
