Libre Office (at least Calc which is the one I use most) is usable but it has bizarre random slowdowns and crashes relatively frequently, whereas I have never once had issues like that with Microsoft Office. I still use Libre Office (on both Windows and Linux) because it’s free but I acknowledge that it has disadvantages.
My problem with Windows is that when I want to eject a USB drive, Windows refuses to do so, refuses to tell me what program is apparently still using the drive, and certainly refuses to kill that program. I am removing the drive. I can’t just not remove it!
