Cloudformation supports more AWS features than terraform.

  Such as? My experience has always been the opposite. Recently, I decided to use Terrform over CloudFormation specifically because you can't create an EKS cluster (with nodes) in a single stack.

    Some specific services (namely Data Pipeline) aren’t supported in Terraform. However, some parameters like Enhanced VPC routing in Redshift clusters is supported by Terraform but not CloudFormation. The rule of thumb that you should generally stick to CloudFormation if you are full bore invested into AWS has some truth. My issues with CloudFormation are lack of control over rollbacks, missing features for existing and mature services like the above, and forcing me to use custom resources to do anything that vaguely resembles coding that Terraform does just fine like IP address math functions.
