I see four different, yet incredibly similar, video conferencing tools on that list. That doesn't fill me with confidence when it comes to just how curated the list is.
I could do a better job on showing differences for sure, especially in that category. In the end, they are all well working solutions, with two of them being free and handling organization differently, the go-to app on the market, and a enterprise solution. All have their own place in that crowded ecosystem.
