Win10 x64 but considering switching that as well btw
Update: I tried Calligra and it crashed in a minute, reinstalling LibreOffice worked tho
Depends.
Calligra has a great interface.
I’m unsure however how it does with importing/exporting documents, and how well it works with OpenDocument formats.
LibreOffice can edit my ClarisWorks documents from 35 years ago and can also open and edit my OpenOffice documents and display them exactly as they were 19 years ago.
