Ask HN: Who do I choose – Fastmail, Hushmail, ProtonMail, or something else?

It's time I broke up with GMail. I've tried ProtonMail and like the idea that they are in Switzerland. Because, Switzerland! I've read about Fastmail and their incredible customer service: I respect CP Botha's opinion and insight. I just saw Hushmail, and that's all I know. The name. Would love to hear some insight on which avenue I choose. I am also thinking about moving my small business as well.
