Qualitatively, AWS is greedy and nickle and dime you to death. Their Route53 service doesn't even have all the standard DNS options I need and I can get everywhere else or even on my own running bind9. I do not use IPv6 for several reasons, when AWS decided charge for IPv4, I went looking elsewhere to get my VM's.

I can't even imagine how much the US Federal Government is charging American taxpayers to pay AWS for hosting there, it has to be astronomical.
