Another point I would add is DNSSEC. With your own authoritative server you actually own the keys and don't have to trust another company.
What's also not mentioned is the possibility to run your own hidden master and use a DNS provider (or multiple!) as slaves. This way you have full control over your zone but you don't have to run your own network of nameservers.
