I use proton as my daily driver for email, calendar, and vpn. Overall the entire suite gets a 6-7/10 for me. They all do exactly what they need to, calendar has been improving a lot, and has a dedicated iOS app nowadays which is a great improvement. I do not use Proton drive or pass so I can't comment on those. But the email, cal, and vpn do exactly what I need them to.
