I like the light touch of the EA7. Those of us who are not, and have never been, piano players don't need or necessarily want heavy action. Particularly now that the wrists and fingers are aging and sore.
Roland did revamp many styles on the EA7, in particular the intros and endings. Intro one is now often useful for a fill/break, which is one feature that is nearly non-existent on all Roland arrangers up to this point.
