Did about half a dozen different flashpoints so far including Steiner and FedRat alliance ones. I wonder if it's RNG or it's actually hardcoded to follow the lore that Steiner payouts are by far superior to other factions.
As an example - for Steiner alliance flashpoint I got a Gauss+ (2 tons lighter than stock) with a grab bag of goodies and a bonus Hatchetman (for running Target acquisition with a proper 320T+ "scout lance" i think), while the Davion's alliance flashpoint rewarded a piddly pulse medium laser and some misc goodies.
