The FM web client loads messages faster, but is slower to use in my experience. I’d rather pay a one-time loading cost up front for an app experience that feels native-ish and snappy like Gmail vs having the app feel laggy when I do mainline use cases like send email or compose a reply.

Re threading I’ve had email for 25 years now and def. feel Gmail’s approach is superior, if only because you don’t have to scroll so freaking much!
