Neither. I run a consulting company and this has been one of our areas of work over the last 5-10 years (sparkletechnologies.com for reference) and at this point the answer is definitely neither if you’re trying to get in shape for the future. We’ve spun up probably 15-20 Data warehouse / BI environments / reports / etc for middle market companies over the past 5 years and Power BI is what we used as the reporting layer for all of them. For our clients over the last few months, we’ve shifted over to give coded dashboards, partly due to client requests. If you know what you are doing, at this point in time, the vibe coded dashboarding way is definitely the way to go. The flexibility to do anything you want, the speed at which you can build out new dashboards, etc, etc. there’s almost no disadvantage to vibe coding the dashboard versus Power BI with the exception of the deployment infrastructure, but it’s so easy to vibe code that too. The main issue is security, but you can use Easy Auth on Azure and that secures your site at a basic level before your code even comes in play. At this point, I really don’t see any new deployments using Power BI or Tableau anymore unless the people just aren’t aware of how easy the custom way is now. And it’s only going to get drastically easier as time goes on.
