I strongly prefer Office to Docs except for multi-user edits. Office on the web absolutely sucks and is miserable to use while a team of people is editing away IME.
You can be using your Excel windows client to edit a sheet, while someone else is editing on a web browser, while someone else is editing on an iPhone, while someone else is editing on an Android phone, while someone else is editing on a Mac.
Sheets is cool, but, Excel and Word and Office365 are streets ahead of Workspace from an enterprise point of view. I've been a staunchly non-microsoft guy for years. When I was younger I was the guy writing it at Micro$oft or more likely Micro$shit. These days, managing multiple companies, some of which use Office and some which use Workspace I cringe when I need to deal with issues on the Workspace side. There are some things which Google does better. Generally APIs for the Office365 products are not as good as the APIs for the equivalent Sheets/Docs/etc product. I've done some fun/funky things with using Google sheets as an adhoc database. Put a "job" in a row in a Sheets sheet and a few minutes later something does your task and you can see the result in that sheet. Super easy to do with Sheets API, I've tried for years to get similar CRUD to work on Excel API and always hit roadblocks.
Office365 APIs for user management and groups and all the "AzureAD" stuff is absolutely top-notch.
Anything Google Cloud or cloud related, google wins hands down.
