Least-Most Chaos-y of the Chaos Legions

While obviously its the case that there are extremely chaos-y and warp touched members of each legion (and, for that matter, probably some very untouched ones as well)... would this be the best order for the least-most chaos/warp touched/warp utilizing (on average) of the Chaos legions?

Alpha Legion

Night Lords

Iron Warriors

Black Legion

World Eaters

Emperor's Children

Death Guard

Word Bearers

1000 Sons
