Honestly, the best ammo for your gun is the cheapest brass care FMJ that feeds reliably in your gun, and is accurate. In factory ammo, I like Winchester & Remington bulk FMG's in most of my 9mm's. The common weights - 115, 124, and 147 grains can all be accurate and reliable, your gun will let you know. The 115's and 124's often do shoot closer to point of aim on fixed sight guns.
For hog defense (I would never use a 9mm for intentional hog hunting) I would think a bullet with a flat point, or TC design, either FMJ, or hard cast, would work best. Id probably look at a 147 grain weight for the added penetration. Companies like Buffalo Bore, Double Tap, and Cor-Bon make specialty loads for such use. I would probably plink with the cheap stuff, and buy a couple boxes of the speciality stuff for use as appropriate while in the woods. On the cheap, the American Eagle (Federal) 147 grain TC might not be a bad choice as well for hog defense. I would avoid any 9mm HP bullet, as most all are designed with expansion first, and would not be good penetrators in something like a hog.
Personal opinion is a good thing, and everyone is entitled to one. The hard part is separating informed opinion from someone who is just blowing hot air....
