It's technically the worst. Without getting too much into my calculations, It has a theoretical kill speed of 1.14 seconds in pvp, if all head shots. In contrast, higher ROF pulse rifles actually kill faster. My favorite, the coiled hiss, has a theoretical kill speed of... 0.94 seconds!!!!! The main reason for this is that in a slow ROF pulse rifle the delay in shooting is not taken into account for the patch dps buff. Fast pulse rifles on the other hand have no delay and so the buff becomes inflated. 0.94 seconds is faster than auto rifles prepatch - 1.0s, putting it on par with thorn and vex (0.8s, all headshots at close range) by being versatile at all long ranges
