Hardlight Seems to shred just as hard as the Doctrine. Feels like it has a bit more range but doesn't kill quite as quickly at close/very close range. I'm not quite sure if it's working the way I think it is, but it's over penetrating rounds should make snipers flinch a bit more too. Plus the weapon is just cool. One of the first exotics I had drop randomly during year 1 from a heroic strike. SUROS Regime and Queenbreakers Bow are also really fun to use.
