I disagree with you! Looker is more advanced, and that does not mean it is better. Tableau’s tools were MUCH easier for me to make ad hoc analyses with, as well as to create dashboard with. Yes, there were some transformations that I couldn’t apply and had to go to custom SQL or ETL for, but the total time to finish my analyses and produce high-quality live dashboards was much less than with Looker.

(I don’t know why you are being downvoted though, you’re entitled to an opinion same as me)
