What makes prefect stand out is the highly pythonic API and the powerful primitives for defining failure scenarios. Additionally, for me, integrating with dask is key as dask has become one of my main tools.

Heres a rewrite of the airflow tutorial in prefect: https://docs.prefect.io/core/examples/airflow_tutorial_dag.h...

My advice is try it out and see if you like the api. I think that the airflow ui is still a killer feature in 2019 though.

Theres also this post from the creator of prefect on why not airflow: https://medium.com/the-prefect-blog/why-not-airflow-4cfa4232...

I haven’t tried dagster yet, how does it compare to airflow?
