Which certification should I do?

As of right now my job is willing to front the money for me to take one of the certification courses and its test. I didn’t realize there were now two of them so I need to decide which one I think would be more useful to the company. We are wanting to upgrade to 2.0 soon and I’m leaning towards the fundamentals so I can get a good lay of the land for changes in the newer version, but the DAG Authoring course sounds really interesting to me and could help with building better DAGs. I would appreciated any insight from those that have taken the courses!
