(SQL Explorer author here) We actually use Looker as well internally. It's a great tool. When we were smaller, Explorer fit our needs really well (I should hope so - since I specifically wrote it for us), but as we got bigger (~40 employees now) it's harder to manage a large number of reports, and we started getting a bit of a backlog of "please add field x to report y" engineering tickets. Looker has been a great solution to allow people to self-serve even more. We still use the heck out of SQL Explorer as well, but Looker adds a ton of additional value (though notably, is not terribly cheap).
