Gmail's IMAP implementation is really buggy. No distinction between tags and folders, non sorting done at the server level, etc. Frustrated, I also moved to fastmail two years ago; it is slightly expensive, but is standard's compliant and works flawlessly.

I should have maybe clarified that i too have moved to Fastmail (about a year ago) and am a happy customer. But both the price and the UI leave a lot of room for improvement, i.e. competitors.

And yes moving mail out of Gmail was a pain because of the weird IMAP structure they use.

I always use a local IMAP client (alpine), so am not really bothered by fastmail's rather basic UI.

I thought gmail didn't have folders; how is it supposed to distinguish the two?

IMAP has tags (rather keywords), that you can assign to multiple posts. Just because you assign a keyword to an email, doesn't mean that it should be moved to a new folder. Gmail does that, and therefore breaks IMAP.
