Maybe after wasting 90% of the whole magazine for the only purpose of stabilising the last few bullets, then yes, it may be accurate.
But whenever that's not the case, a hyperion weapon probably wouldn't hit something at close quarter combat.
TL;DR, Dahl for the win.
Asssault rifles from Dahl and Vladof are usually my main 'power weapons', with others being things like SMG's and elementals for other tasks
Also, it seems very useful using a slag weapon when your turret is out (Assuming you're a commando), especially against big enemies
