Funny, I recently departed from the google ecosystem to proton, self hosted nextcloud, kagi, Libreoffice, and Apple Maps. Am I giving up some ease of use? Absolutely! Can I live with it? Absolutely! Can google go fuck itself? Hell yea. Libre office is like missing a limb, but with practice it can do anything I want it to.
Google, Excel, Numbers, LibreOffice, close enough as makes no difference for what the vast majority of people do with spreadsheets. And even for more complex use cases, any of them will most likely be fine. Google probably has the edge if you need real-time sharing with multiple people.
