Maybe it’s just me, but I have serious issue with Fastmail’s spam filtering. Meaning, it seems that I am the spam filter. I find myself considering closing the account on a regular basis because of it.
I am also extremely frustrated with Gmail’s AI features now being apparently impossible to disable.
Fastmail's spam filter has been better than Gmail's spam filter in my experience.
Thier spam filter is really great, probably only one time they flagged a legit email as a spam. On the other hand, the email I have that uses fastmail never ended in someone’s spam.

I had issues with it early on, and after some back and forth with support they explained to me what is going on: it takes about 200 spam emails before your personalized filter kicks in, before that you might see something slip through. Also, the spam filter updates after you delete emails from your spam folder. Just remember to empty your spam folder, and add some custom rules until you reach that 200 threshold.
5+ years in, everything is working great, nothing to complain, best email provider I've ever used. I only wish they had servers in the EU.
