LibreOffice 7.3
I find LO to be very buggy and unintuitive in its UI. Equations are a pain, it forgets styling options, etc..But as a user who uses it completely independently of MS Office, just for my documents, the peace of mind I have knowing I am using a powerful multiplatform open source software which won't betray me is priceless.I know my documents are safe and I can move between OSes at my will. This kind of freedom is essential for me and I am grateful for that
