Personally I much prefer Fastmail to Gmail. The site is way faster and more cohesively designed. Fastmail supports jmap, and way more imap extensions (including push support on Apple mail). They have helpful humans handling support requests. And they do all of that with what seems like 1/10th or less the number of employees.

The only thing I like more about Gmail is their native mobile apps. Fastmail’s official mobile app is a web view.
