Ask HN: Choice of secure private-data email host?

I've been meaning to switch off Gmail to something that doesn't copy my data as its subscription fee. Preferably something that's also secure against e.g. generalized external monitoring or govt. requests, presumably by supporting PGP.

I've found three different possibilities (FastMail, ProtonMail, and Runbox) without even particularly looking; I am having difficulty comparing much about them beyond their price-points. Presumably other such services exist that I haven't found.

What would the HN crowd recommend for this?
