Tutanota vs Proton Mail for daily use

Hello, I am thinking on which email provider to use as an alternative for Gmail.

I don't expect E2EE because I know nobody who uses either Tutanota or Proton Mail personally. I just want an alternative to Gmail, where I can message people I know who use Gmail securely.

EDIT: I have chosen my email provider as Proton Mail because I can send encrypted emails not only to people using Proton Mail, but to people who don't too, which I feel is better.
