I agree that the .96 deco is arguably the most powerful gun in the game. It has almost no downsides and lots of upsides. One could argue that the RNG is a downside though. You get a much more accurate gun with splattershot pro, and sometimes (with the .96) it is frustrating to not hit what you are aiming at. Fortunately, I've only encountered a handful of good .96 deco users. Most I run into treat it like a .52 and try to rush people down.
