Well
How do you buy motor oil? I buy bottles that are green, because I like green. Most people do the same thing, but probably wouldn't admit it. The same people buy hollow points based on similar criteria, like the packaging, the name, how evil it sounds, how evil it looks etc. etc.
If you only had to pick one hollow point, I would pick the Hornady XTP because it is a reliable feeding bullet, that expands but still penetrates. It's kinda like airing on the side of caution. I've used the XTP for deer hunting and they have performed flawlessly. Deer are about as similar as any of us are going to get to testing on people (thankfully). They don't sound evil, they don't look evil, but they do work.
