Guitly Spark is more mysterious.
Cortana works for the humans, GS works for the Forerunner, but they are gone.
He now does what he thinks is the proper course of action, and he controls legions of floating laser guns(sentinels).
Also he strikes me as much smarter than Cortana, when he realized there was a AI in the core he wanted to start deleting it immeadiatly, but Cortana threatened him with the Deletion of the Index,. without that Cortana would have been history, Same for the Galaxy too I guess....
