Protonmail is one of the last sane email providers. Gmail is essentially spyware and they can block your access to your account on a whim, especially if you refuse to have a phone number connected to it (phone numbers are commonly used to link your account across many different websites, that's why many of them force users to hand over their phone numbers under the guise of "security" or "2fa").

Protonmail has its problems but I hope they get over them as a company. Personally, so far I've received nothing but great customer support from them.
