I used @libreoffice in grad school and it was great. Got into Windows stuff for about a decade (❤️ Nokia Windows Phones). One day last year I realized how much space Office was taking up on my Surface Pro with very little storage (3 GB versus 700 MB). Reinstalled LO and have been very happy. The AI madness at Microsoft has been leading me to gradually get rid of as much Microsoft stuff as I can. It's a task because I have used MS services heavily.
