Microsoft's O365 stack and Teams aren't great, my friend, but they're light years ahead of anything Google and Slack offer. Especially when any sort of collaboration is involved.
The collaboration features in 365 fuck up and get in the way a lot more often than they work correctly WITH ONLY TWO CONCURRENT USERS. Conversely, I've seen entire classrooms in Google Docs working together like it wasn't even a thing.
I don't have a lot of love for any of these companies, but what you are saying is objectively false.
Completely wrong. The Microsoft word collaboration is completly Terrible, constantly locks other people from editing even if they are on another part of the page. It really doesn't work for more than 2 people, while you can have like 30 people on a google doc with no issues (probably more, haven't tried more).
Also, I blocked beehaw, why can I see your comment
I can't dispute that. I'm not a Word person. I live in Excel and often have half a dozen people working in the same file without issue, but that's much more logically structured than a Word document. Google's team sites are also disjointed and janky af compared to Sharepoint.
