The Devil You Don't is easily the worst legendary hand cannon. It's in the high rate of fire archetype but, that's about the only plus, lol..............it is the second slowest reload speed of any legendary, has low range, mediocre stability, and (an abysmal) 5 round mag, completely useless, lol. I actually bought it, and almost immediately discarded it. Unfortunately there aren't really any "great" vendor hand cannons (for some reason we went from having 4 vendor hand cannons pre DLC, most of which were really quite good, to having 3, and only one of those (The Chance) is worthwhile). Of course now that hand cannons are getting a nerf I might be using scout rifle all the time instead so I guess it doesn't really matter.
