Proton drive’s docs are just starting to be good enough that I would recommend them, but they are far from feature parity with google’s. Just try to make a PDF of a word doc, copy cells that are used in equations to a different sheet, or create a presentation.
Tuta could be a real contender if they wanted to be.




























I would love to hear how collaborating on docs works in nextcloud. Or really of any open source solution that does collaboration well.
They may exist, I’m just ignorant
