You're right, actually. I've dealt with all three, AWS is definitely more friendly (if we're talking about support here) but they all have the monopoly. AWS, honestly, is the only one that actually has an advantage. Verisign is overpriced, GoDaddy is just a typical domain registrar.
Could you justify your relating? Your relating basically suggest any one's father is any father to his son/daughter. I could not agree that for any child, they are fathers treat them equal good/bad...
In summary, it's find to be alert, but be sure to not over-generalize...
(Obligatory) Apart from the single political point of control. AWS is to web apps what GoDaddy is to DNS and Verisign is to SSL.
