The video conferencing on Matrix has been really good for me so far. FOSSDEM 2022 was hosted on it and that really sold me on Matrix as a solution tbh. The recorded talks played smooth, and the chats worked no issues, while the break rooms gave me that genuine "I'm actually at a conference" feel, because it was so easy to just join a room and talk with our cameras on and everything.

Teams has been mostly up and working for me, but we have "sorry teams wasn't working" issues all the time, so that bar is low to me. Even more, matrix better fits larger organizations that frankly should be using the federated approach for a lot of things, and stop trying to have IT policies that fits hundreds of thousands of employees over large geospatial distances.
