Maybe it depends on what you work on, but i havent seen powerpoint or .docx file in like a decade. Everyone i know uses google docs.
I'm sure there are users with specialized needs who need something more complex, but i dont think microsoft office is quite the moat it used to be.
Trade one devil for another?
I’ve never looked to see the compatibility of Office to Gsuite.
So unless it is 110% perfect it is a non-starter. The second we have a supplier send an excel with some goofball formula in it and we don’t see some data or can’t open it - it’s over.
This isn’t even getting to the next devil… Adobe.
My employer blocks access to Google Docs as part of our confidential information protection policy. They're certainly not the only ones. I'd hesitate to call on-premises file management "specialized needs" - rather, it's (still) the default, particularly if you take a peek outside of the software bubble.
I suspect that that is more an anti-shadow IT measure than an anti-google docs measure.
