Unfortunately, Word is light-years behind any alternative, open source or not. Styling is a half-assed inconsistent mess. Bullet indentation jumps around like crazy. Changing your default printer might cause reformatting. There is no decent separation between content and formatting. The menu ^h^h^h^h^h^h ribbon is such a mess you need a search function. Word is the kind of product that should be taken out and shot. I speak as someone who used word competitors back in the days when there were some left.

Now if you say Excel, however, we might start to agree.

BTW, while Gimp is not a photoshop replacement (please fix the window behaviour, guys) but krita is getting really nice, and plenty good enough for your average corporate user.
