Is there a distinct advantage for one vs the other? For example, if you build the Nataruk with Galvanized Chamber, Hunter Munitions, Shred, Critical Delay, Vital Sense, and Serration, you can either go pure slash with Heavy Caliber and Vigilante Armaments or viral with two elemental mods. If I understand correctly, the pure slash has bigger slash procs but the viral amplifies the procs.

Any thought process on the difference between the two selections?
