For me it was their app just being so far behind Fastmail.

If they had a better app I'd gladly pay. I just can't stomach gmail anymore and Fastmail was next best.

Amusingly enough, Fastmail is a web app wrapped in WKWebview and Protonmail is a truly native app.

Based on comments over in /r/protonmail there's some redesigns coming for the apps that should hopefully improve on the creature comforts.

I hope this is true because I like the privacy aspect of protonmail and would pay for it in that case.

How do both of these compare to Thunderbird?

I haven't used Thunderbird enough to answer this
