I've had my own domain since the early 2000s and have never needed to run a public dns server. Couldn't, in fact, due to not having a static ip address. Sure, I run one internally but it's complicated enough to setup "properly" that I leave the external resolution to the big players. I doubt anyone's home setup will be more reliable than route53...
Commercial dns services are cheap as chips and make it easy to add records. You can often automate it with terraform or sensible as well. I can't think of any good reason not to use one.
