I like that it's easy for me as an individual user or business owner who has little technical know how (how hard can this be?)to manage my own domain names! It makes managing multiple domains much easier than having them all in one place with DNS services such us Cloudflare/DNSimple etc., which are more expensive but not necessary if you have your hosting elsewhere already - especially when using managed service providers of these kind because they usually take care about things related security issues while keeping everything else under control so we don't need additional IT employees just do our job right away :).
