[author of Airflow here] as I wrote in another comment, I'd argue for a programmatic approach to workflows/dataflows as opposed to drag and drop. It turns out that code is a better abstraction for software: https://medium.freecodecamp.com/the-rise-of-the-data-engineer-91be18f1e603 https://medium.freecodecamp.com/the-rise-of-the-data-enginee... I'd also argue for open source over proprietary, mostly to allow for a framework that is "hackable" and extensible by nature. You can also count on the community to build a lot of the operators & hooks you'll need (Airflow terms).
