Disclosure: I work on Astronomer.io, an open source Airflow platform and SaaS, and also contribute to Airflow.
IMO the pros / cons are really relative to what you're comparing it to and what your workflow needs are.
We've written some guides on "Airflow vs ___" [1] (currently AWS Glue and Oozie). Feel free to email me (in profile) if you'd like to see a comparison to something else.
I like these two posts on Airflow vs Luigi, Pinball, Azkaban, etc [2][3].
