From the users perspective Microsoft Teams satisfies the needs

It does get new features from time to time, but mainly because they have been incredibly responsive during the pandemic. I can still remember that I used the software at [university] before the pandemic struck and we didn't notice many obstructions when we suddenly had to do everything through Microsoft Teams.

With little technical knowledge, you will be able to use Microsoft Teams just fine. Without it, though I can understand it can be difficult to connect your audio and video input and make sure everyone can hear you, especially when you've got multiple devices hooked up to your machine. It will work great for most and that's what counts.

Within bigger organizations as well as smaller ones Microsoft Teams handles calls well. I do however recommend not all turn your camera on or start screen sharing when you're in a call with well over 50 participants, because then it may experience some connection issues. For normal use it is perfect, outside of those boundaries it does not have much more to offer.
