Yeah the $10/mo plan for Pritin is actually super good, and they have a whole suite of tools that covers basically all you could need. Though I've been liking Tutanota, and they just announced an e2e cloud drive so I'm patiently waiting for that. I feel like if I wanted to get proton drive, I'd have to go into their whole ecosystem and don't really want to migrate my setup and like the Tutanota company.
