for me:
- google drive > pcloud (objectively better app tbh)
- chrome > librewolf > floorp (i like having the tab bar at the bottom, and librewolf is a bit annoying sometimes)
- photos > ente
- gmail > proton > tuta > "disroot" (proton and tuta aren't IMAP, and their first-party apps are slow. disroot probably isn't the best one, I just chose one that supports IMAP)
- google search > ddg > SearXNG
- google office > onlyoffice on windows, libreoffice on linux
- google maps > Organic Maps
- google passwords > bitwarden
- google auth > ente auth :)
