Same/similar here. The biggest issue for me was when the big players 
demanded SPF and DKIM. That was around 6-8 yrs ago if I'm not mistaken. 
There are tools on the net which can verify your setup, e.g. mailtester 
[0]. That was very helpful at that time. Other than that, I never had 
troubles [1]. Outgoing mails mostly end up in graylisting, but that's 
acceptable. The stack I use is exim, spamassassin, dovecot on debian 
stable since ~2006.
In addition to the reasons above, I also learned a lot about how email 
works and I was able to tweak exim config in a way which is only 
possible on a self hosted system.

  1: My VM got hacked just after I started it due to a vulnerability in 
     exim. Lesson learned: Read debian-security mailing list and keep 
     system updated! But I was still young and re-installed everything.
