I always like to pick grand names that can pull explicit images to mind. Rage Of Angels is more descriptive of an emotion similar to rage, which, being from heavenly angels, is an emotion so grand that it's impossible for humans to understand it (but fun to ponder).
Another name of mine is Storm of Swords. There aren't many things that can beat the terrifying image of swords blowing in the wind.
Rage (Also, Rage of Angels shortened is just Rage, which is a cool nickname)
