Why do people like screwdriver again?

Recently decided to try playing with one variant for all weapons. Blue and red was fun but green is where issues started to pop up, just gona say it don't like the screwdriver. I wouldn't call it terrible, good for new players...But feels like i'm missing something. P rakned everything on Brutal without ever really using it before, I know about punching the drill between enemies but even with that screscrewdriver feels like the least versatile out of the railcanons. electric has good damage with infinit pierce and being able do to +conductor is quite nice. Malicious is just a big explosion. And the drill has? Being able to instakill Maurice, cool I guess. Found it rather annoying that it can't instakill stuff like soldiers or Streetcleaners. And, call it skill issue if you will but why is it so hard to hit? I swear the beam from electric is bigger then the drill projectile, at least it sure feels like it. So any tech am I missing?
