Libreoffice has always just worked for me, but I don't do anything special with word.

I've also heard that OnlyOffice is very good and has better compatibility with Microsoft's formats, but I've never personally used it.

Ok! I can just use Google docs! it downloads automatically as a word file and it looks in word pretty much exactly how it looks in Google docs

Personal Office is a total waste of money

> The only issue with linux I am wondering about is sharing my CV where most companies need a word file.

Maybe it's regional, but I've never been asked for a Word file resume.

I've never had somebody turn down a PDF. And all of the "Upload you resume" online applications I've seen also support PDF. A lot of them lately will even correctly parse out the info and auto-fill forms with it, but some of them mangle it.

For CV I use libreoffice and save it as a PDF/a. If it needs to be editable for some reason you can use docx or odt(odt might scare the average office worker so stick with docx).
