When you eat home grown vegetables, the experience isn’t objectively worse. When you run your own mail server it is.
If you were running your own restaurant and your home grown vegetables caused a worse customer experience would you do it? Running your own mail server which causes more of your mail to go to spam is worse than using a commercial provider.

^ I both run my own mail server and use someone else's service for another purpose. My experience running my own mail server is objectively WAY BETTER than using the commercial provider (and I've been doing this for many years in multiple scenarios).
Just because your experience (even if it is repeated) with certain technology goes one way, that doesn't make it universally true.
It’s not “just my experience”. It’s practically a universal experience that the chance of emails sent from your mail server will be blocked or go into a spam folder a lot more frequently than using a commercial provider.
Of all the questions I have to answer on technology decisions, why would I want to answer why did I choose to run my own bespoke mail server instead of spending a few dollars and making it someone else’s problem and so metaphorically chose IBM - ie “No one ever got fired for buying IBM”.
