I’ve been dual-booting Linux and Windows for a while, with Windows as the fall-back option in case I wanted to use Office for something. Now that they tried to trick me into paying a subscription for their AI slop machine, I’m finally, fully out. It was a pain to actually track down and back-up the stuff that was held for ransom in OneDrive, but now it is done.
LibreOffice has more features and is overall better. OnlyOffice is more compatible with MS Office. So if you need to use docx etc. for work, you use OnlyOffice as a workaround.
But LibreOffice has supported docx for years now, right?
It messes up object arrangement. This is technically Microsoft’s fault, but that doesn’t help when you want to communicate clearly with a MS Office user.
It has some weird formatting issues iirc.
