LibreOffice is more than slightly worse, but FOSS projects cover the gamut. The thing about them is that the best ones are usually laser focused on exactly what the user needs, rather than what makes the most money.
Calc was actually quite comparable for 90% of Excel features I have ever actually used.
Writer is petty good on its own, but the fact that .docx documents don’t quite matchup vs. When making and opening with Word makes it difficult for me to use officially.
Impress is just plain disappointing compared to PowerPoint.
Base might be okay, better than nothing I guess.
The rest of the suite I don’t know.
Dont edit in shitty formats, edit native, publish to pdf. Skip the pointless MS Office step. If someone else wants to collaborate, great they can download LibreOffice or alternatives for free. If they expect the docx format ask them to pay for your 12 month subscription or stfu.
