Depends on what you do with it. In accountancy we and most of our clients work with Microsoft Office desktop. Also things like templates based on CRM work better with actual Word.

Edit: Libreoffice is also a bit annoying since the settings aren’t in the same layout so helping others becomes harder. Not sure if they implemented it since I am not that well versed with it as with Excel, but I belief they don’t have a PowerQuery alternative?

Does the dualboot of Mint cause any issues for Windows? I only tested it very briefly on somebody elses machines where I needed to wipe windows and install Linux
