| Looker is obscenely expensive compared to Tableau. Also the UI is bad. The caching of Tableau is a huge money safer and huge performance boost if you e.g. use it with BigQuery (cut our BG costs by 80%). As with every data tool, you need strong data governance, or everyone will define their own metric for revenue and then you have endless discussions about "why the data is wrong" (it isn't). The biggest benefit to me is every marketing person knows Tableau and with a self explaining table structure (e.g. DBT on top of BigQuery) is self serving. The only good thing with Looker is their data journeys, which Tableau doesn't have. The worst (for EU/GDPR at least) feature of Looker is how people can send emails from a query (circumventing corporate email infrastructure, blacklists, data protection etc.). Can you say "Intern sends spam mail to millions of customers because they thought this was a good idea". |
