Their use of algorithmic prices means that you can sometimes get domains on GoDaddy for cheaper than other registrars. Price is something that is hard to argue against.
Between their customer service, their ethics, their past poor behavior, their shitty admin, etc I would happily spend a much greater margin for !(GoDaddy) than I've ever seen in .com/,net/.org type domains. (And the ones that vary more between registrars aren't even available on GoDaddy anyway.)
