I still have a @gmail.com account and every time I check it there's a whole lot of spam sitting in the inbox waiting to be classified as spam. Very strange as my main address (which I've had as my main address for almost 20 years) is on FastMail and hardly gets any spam despite the address being much more exposed e.g. it's found on many public mailing lists and it's been part of more data breaches than I can count. Yet it's Gmail that gets the torrent of spam including many obvious ones ending up in the inbox. YMMV of course but I don't rate Gmail highly compared to FastMail and even Office365.
