Sheets is awesome and has a lot of power, but it’s constrained in the browser and is defined by its competitor.
The other issue is that you don’t see as many power users of Google Docs and Google doesn’t have a clear strategy. For example, they could easily make a power bi type tool on top of Sheets and Slides.
I didn't know about Looker, but my BI needs are modest and Data Studio is free and simple enough.
Looker is a third party solution right? Or does Google offer Looker directly in some way? If you're up for sharing the pricing for looker, I'd be curious (the looker website has a request quote button, so I'm guessing it's not cheap)
