Honest question.. how long have you had the email addresses you're using for comparison?
I've had the same email for the past 12 years, corporate, and now moved into O365. It's _average_ for spam filtering as far as my subjective experience goes.
Marketing emails go into "promotions" - but I could probably unsubscribe from those if I wanted.
The only messages in my inbox are either from real people or are otherwise notifications I want to get.
