Like the simplicity of integration AWS resources with Cloudcraft.

I think Cloudcraft by focusing exclusively on AWS diagrams is great. For instance, the components are not merely visual blocks, they have additional semantics and behaviors. If you select the Lambda component you can specify the memory, requests and running time, and receive the cost estimate. Select an EC2, choose the instance size and see the machine specs, costs and visuals all update at once. Next step: connecting your diagram with your live AWS environment! isometric views are pretty, but flat diagrams are much more readable.

Very easy to do both quick and dirty diagrams, as well as extremely large and in depth diagrams. You can connect your AWS account to Cloudcraft to list your used resources and costs.
