I switched to mint like a month before PewDiePie lol
My main issue is that I kinda need actual Excel every so often because I require things like power query. I tried installing it using Wine, but it needs to authenticate with Microsofts servers, even the older versions.
I switched over to EndeavourOS around the same time. I relegated my old windows install to a virtual image, which I boot into for specific games and Excel. 10/10 recommend.
OnlyOffice is worse (and not because of the security breach implications), but because it misses the Ctrl+D shortcut (copies the cell above to the current cell). Which is something I use A LOT for data entry.
