I've hosted my own email server for years; I coincidentally shut it down yesterday. Once you've got it set up properly, deliverability is quite good. The main problem is having to monitor blacklists, spam and account brute-force attacks, and typical issues with infrastructure such as disk space or DNS. Rarely anything goes wrong, but when it does, it will be at the most inconvenient time and you'll have no option but to fix it if you want to keep receiving email. Out of principle, I believe any individual should be able to self-host, but at the same time, I don't have the time and interest anymore to babysit servers for personal use. So you probably want to weigh those two things according to your own situation. The main issue these days is finding providers that allow running open mail servers and yet are not blackholed because of IP range sender reputation. A lot of the cheaper server providers have to fight relatively lot of abuse so you're stuck between a rock and a hard place having to convince both your own provider as well as the mail servers you send to of your good intentions. There should probably be a provider aimed specifically at email servers that takes extra care it has IP ranges that never host spammers, cryptocurrency, tor nodes, botnets and whatnot.
