The worst thing that I've found with teams is the latency in a video call is _just slightly_ too high (and noticeably higher than Google meet and zoom). I find this latency to be absolutely critical in keeping the flow of conversation and preventing people from accidentally talking over each other. After seeing a forced switch to teams when the whole company was WFH, it was extremely obvious the detrimental impact it had on every meeting. It's the most basic technical aspect of the product, it doesn't matter how great the rest is if you don't nail it. That's why I hate teams.

Also the ux is pretty bad.
