Also have you read the Forerunner Trilogy?

The Forerunners are just one level below the Culture now, and the Flood could make the Tyranids look like a fly in comparison. The Precursors are just Xeelee without time-travel and Ancient humanity are still several levels above Necrons.

The Haloverse is now above both WH40K and Star Wars by a huge margian.
