This. It is truly amazing how many in this thread have 0 clue about MS products. I guess GSuite is amazing if you are a 2 person company. Everything above that is on the Office 365 train.
There are plenty of companies with tens of thousands of employees using GSuite [1]. Also various governments, agencies, regulated industries and so on.
A few years ago, GSuite added improvements to Office importing (primarily Excel and PPT, IIRC) that assuaged a lot of folks. Companies still might have departments using Office (e.g., Legal still using Word for its redlining or Finance using Excel) but because you can shove them all in Drive or import them into the GSuite equivalent, most of the company happily uses GSuite for everything else.
MS teams only comes up when you talk to lawyers, accountants etc more legacy or enterprise companies.
I’d think there is something wrong if I see a tech company on MS office. Either they are clueless or they want to save costs.
