Looker is a lot easier for business users to do simple ad hoc analysis in my experience.

Periscope is easier to turn basic SQL into visualizations and dashboards, Looker requires you to do some extra modeling to get it working.

I've used both, and strongly prefer Looker. But Periscope is likely better for small companies where SQL writers are the only one that really need to do analysis, and does this job pretty well.

But a big congrats to the Periscope team!
