Metabase is more user friendly and totally targeted at non technical people. Setup is super easy and it supports all of the most popular datasources.

You can give meaningful names and descriptions to your tables and columns. This helps the end users when they are creating the queries (called "questions" in Metabase). Question creation is all done visually, you can even join tables and do aggregations (group by) without coding any line of SQL, although SQL can be used for more complex cases.
