Granulated garlic is to fresh garlic as (blank) is to (blank).
As pepper flakes are to habañeros?
As decaf is to espresso?
As Brad Pitt is to George Clooney? (I guess this one depends on your taste. Maybe the other way around?)
The point is that granulated garlic will never have quite the zing of the fresh, but, as my family says when we're seeing the glass half full, it has other attributes.
