I was comparing them yesterday with the IB Vendor Roll and the Raid drop I got. Raid had way more stability and more ammo. Impact seemed the same My Ruin Wake more or less put them both to shame with stability. I didn't note the IB nor purchase it so I can't give you a comparison. However I can only give you mine on my Ruin Wake which I seriously dig in PVP. Also my stats are primary based on my current rolls and what I have upgraded and what I haven't. We all know once you change perks guns get better or worse. Stats......Ruin....Raid Rate.........66.......66 Impact.....55.......55 Range......25.......18 Stability...65.......50 Reload.....32.......16 Mag..........35.......58 My Ruin wake is on my Warlock and my Titan has my Raid Machine gun.
