CloudSpectator sells its analysis to enterprises and providers. They will benchmark internal systems to help an IT department figure out the total cost to move into the cloud. They also have two free offerings. One is a series of reports about cloud costs, performance, and other data, similar to CloudSquare.
They also have a second offering that provides interactive reports on seven providers: Digital Ocean, AWS, Rackspace, Google Cloud, Century Link, Profhost, and Microsoft Azure. All this information is presented graphically, which makes for pretty charts but not much in the analysis department.
