Go Daddy's DNA service is one of the best in the world, their DNSSec is the best I have ever seen, and they offer a variety of niche items like vanity name servers. Plus they often sell domains at a loss and the next ten largest competitors for actively served authoritative zones don't add up to what they do. Now if Google really becomes a competitor I bet Go Daddy would do something to run the tides like start offering free premium service or increase thier infrastructure. All of which would be amazing.
