FWIW, I use MIAB and my e-mails aren't dropped regularly from what I can tell. Before this, I was using a mix of CPanel and gmail but for a variety of reasons, I wanted to take greater control of my e-mail.
I signed up with a small VPS/hosting provider that offered a decent amount of storage space with their VMs. I don't send spam and have maintained the domain name for a lot of years. I checked the IP for blacklists before migrating the domain to it. I may have had to e-mail one blacklist provider about being removed but if I did, I don't remember it.
Since MIAB sets up DKIM and SPF, your deliverability is pretty good out of the box. I don't send spam and so I think the IP's reputation has been getting better and better over the last few years. The truth is that for personal e-mail, the majority of messages are inbound and that's really not a problem.
