So being the newbie that I am to handguns I am going to pose this question in hopes of gleaning some knowledge. This is NOT to start a feud or angry debate. I am looking for answers from both sides of the fence. So here goes:

During my hog hunt I shot the Barnes XPB's. I also loaded (but didn't shoot yet) Hornady XTP's. After looking at quite a few threads here I see recovered bullets that haven't expanded much at all. I was blown out of the water with the expansion and penetration of the Barnes bullets and figured that was the cats meow.

So which is better; Minimal expansion with excellent penetration or maximum expansion with excellent penetration?

I know there are a number of factors involved but in the pistol world I am wondering what the "best" is.
