Whether it’s -0.1 or -0.9, I think the loot table is the same. Other than being specific for the Faction in that area, I think the main aspect affecting the drops is the RNG chance being applied to each Hack.
Hacking is generally semi-worthless clutter, because datacores are the simplest way to cash out FW LP thus tons steadily dumped to market.
