I think Microsoft is easier to use for formatting (and heck, I get it free because of my university), but google has the convenience factor of being able to access anywhere. I’ve connected my Microsoft account so I can access from my laptop or phone, but that still requires having either. I’ve started carrying around my laptop more as a result, but it’s a gaming laptop and kind of heavy >.>
Technically I could get access to Word through my Uni as well, but I don't really need it since I am using Google for everything. Plus, I wouldn't be using it for personal stuff, only school.
