I'm sure there are other services that are cheaper in some of the areas, but at least the argument about "insane complexity" is moot; if you've used AWS before it's no problem to set something up from scratch. I've done it numerous times and it's a one day job to setup most of the infrastructure required with VPCs, IAM users, policies, databases, scaling groups, storage configs etc.. That part of it is not really an argument to switch at least.
