The way it integrates with other applications is really nice, like Salesforce or MS products (Outlook). It also has great integrations for monitoring server health etc. I would have liked to see more customizations in the UI but that's an easy fix when they make new versions of ESD. They seem to be constantly adding features so we get better tooling every time there is an update. We use ESD as our build/deploy system for any application changes coming out of our main development environment. This allows us to easily deploy code without having separate scripts for each task.
