I would have said Paleocontact (Destiny)

I'm not a huge autorifle guy in general but have all three of these. They share the same archetype. 88 RoF, 8 Impact and then the rest of the stats vary.

Paleocontact (Dead Orbit)
Haakon's Hatchet (Iron Banner)
Righteous VII (New Monarchy)

The vendor Righteous VII is a really solid gun with perfect balance, rifled barrel and glass half full. I have it equipped on my hunter currently
Red Spectre seems to be an awesome looking autorifle by the stats. It's a crucible reward drop but has the 88 Rof and 24 impact instead of 8. If you could get this with a stability perk and a range perk then that would be a beast.

Out of the ones I have, the Righteous VII is probably my favorite so far. The vendor version is nearly perfect with the added range and stability and glass half full.

I had two drop last night that I want to try out also. I got another Righteous VII with high Caliber Rounds, Rifled Barrel and Rodeo. I also had a Dealbreaker drop with Glass Half Full, Crowd Control and Rifled Barrel/Hand Loaded/High Caliber Rounds.
