Rank the Heralds

How would you order the heralds of Galactus from first to last ?

Silver Surfer, Morg, Terrax, Fallen One, Red Shift/Firelord, Nova, Air walker

SS, morg, fallen one, stardust, firelord, airwalker, terrax, redshift, nova

I know I'm supposed to make a list, but I wonder why Marvel doesn't bring back Fallen One as a rival to Silver Surfer.

I noticed nobody ranked Dazzler...
