AC-130

There is all of this hype about the "amazing" AC-130.  Now I put amazing in quotations because I do not find it to be that great.  The most kills I have gotten with it is at most 5.  I just don't seem to be able to do very well with it.  I always either miss or for some reason it just doesn't kill them.  I prefer to just use the Chopper Gunner due to the fact that I can get about 10 kills with it.  What do you prefer? AC-130 or Chopper Gunner?
