Work issue MBPs but we also extensively use Google Docs. At home I use MS Office on !y desktop but also have a Linux laptop so Libre / Open Office.
If you’re using a lot of advanced functions, formatting and that kind of thing then you’re better off using the same software across the board. If it’s more basic word processing then it’s rare to get a problem.
As I rarely us anything more complex than page breaks I manage just fine swapping between the three and using Google Docs for much of it. If I have a more specific task with references, indentation, lists and the kind of thing used in more technical documents then I use Office (MS or Mac) just because I’m faster moving around its interface. I can’t remember the last time OO or Libre messed it up though.
Not a technical or specific reply I’m afraid but neither is my use of the software. IME, in general, you’ll be fine for all the simpler stuff.
Give this a read.
