What is the best cloud storage provider right now? - eviltoast

What is the best cloud storage that gives a nice balance between features and privacy? I know you can manually encrypt files to use any provider, but I would prefer an open source E2EE for the sake of convenience.

Currently I have heard about the following:

  • proton
  • filen
  • sync
  • icedrive
  • pcloud

(Not including GDrive, Onedrive etc…)
