I'm currently using Winchester Ranger 147 gr JHP (RA9T), which is what my agency issues for 9mms.
I don't believe that one particular brand and load type has any more 'stopping power' than another; I'll use any good premium quality, standard pressure 115-147 JHP load from Winchester, Federal Remington, or Speer that is 100% reliable in my carry pistol.
If forced to decide on a preference, I'd rather use 115s for general personal defense, especially at home, but I prefer the 147s for patrol work, where I might need more penetration.
