Before I decided to leave it due to its horrendous false positive rate, gmail was driving like half of notification emails from my servers and mailing lists to spam, despite me never marking them as such. I was regularly missing important things.
It's much better with just regular client side bogofilter and some training on my personal mail/spam archive. And I do zero server side filtering, it's just all content based.
I don't care about capabilities, I just want near 0 false positive rate on the kind of email I receive (and not some common model), even at cost of some false negatives, and Gmail doesn't deliver there at all. And I don't want any arbitrary 5xx rejections for my senders, since I know how annoying that is on the sender side. Gmail will not guarantee that.
No, sorry, it's purely anecdotal. And also more applicable to the last few decades, when other email services were still terrible, than nowadays with many adequate options.
I think I have the opposite preference to you: false positives are OK to me if that means less spam gets through. In fact I've seen many of those notifications in my gmail spam and thought to myself, "Huh, you know, maybe I don't need those that badly after all... I'll just let gmail keep it there."
The overwhelming majority of my human contacts use other channels anyway (some chat app, or SMS), not email. I might get like ten real emails from humans in a year, and even then 90% of them are from people already in my contact list (and so bypass spam).
Phone calls are similar these days. Google Fi/Android also applies a similarly strict spam filter to incoming calls, and marks and blocks a lot of them as spam. I check once in a while, but overall I just don't really mind. If someone really needs to reach me they'll find a way... if they don't try, it's a good filter for how important their message really is anyway, lol.
