Humm…
In my case, with all Spotlight options enabled, Spotlight got 66 hits on "installer", EasyFind located 67 items.
What I like about EasyFind is the "Reveal In Finder" feature which allows one to easily locate and delete deeply buried or invisible files. Also, I am partial to the ability to sort the results in alphabetical, where, or created date order.
To me, EasyFind is indeed an adjunct, not a replacement (though I do use more frequently).
