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.

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.
