We assessed it.
Long story short: product is not mature enough.
To import your image with AWS Workspaces, you must run a compliant script manually (BYOLCheckerScript), which is a real pitty. This limitation comes from AWS and they don't want to hear anything about it.
Power Policies to optimise costs are not ready yet.
Multi-Session is not ready yet.
It's cool, but will be a good product in a year or so (mainly because of AWS, not Citrix teams).
