I liked Skype, simple to use. I absolutely hate Teams, way to complicated. When I worked for fedgov many shared the same opinion and refused to even turn on Teams. Maybe someone else can purchase the rights to it and do something with it again.
Working in sales... my customers often wanted to set-up video conferences to monitor projects. Every company was standardized on their ‘favorite’ system.
For me, Zoom was the easiest to work with. But customers that were heavily oriented toward Microsoft products would require us to use Teams. My impression was that Teams was a bit too complex, but I’m sure that had I used it more I might have felt otherwise.
It does seem that to get the most out of Teams you have to have the entire Microsoft suite of products.
