I have used LibreOffice for a decade now, not just at home, but including company work where others are using MS Office/365. Haven't run into any compatibility issues in a long time (years).
I wouldn't give MS a nickel for MS Office/365 these days.
I still use Office 2003. There is nothing wrong with it and it doesn’t have that indecipherable ribbon.
Sometimes I just want to set my own margins and just type a simple letter, personal or business without fussing about with preset columns or having my cursor thrown about and with issues every which way. Sometimes I just want type writer functionality then save as a pdf or word document. There is a hard learning curve for all the various controls and wonder presets with bothe Office and LibreOffice.
