Realtree AP HD for me. But I figure camo catches more hunters than game, just like most fish bait is designed to get you to buy it more than get fish to bite it. I have used the old fashioned army woodland camo which doesn't look like anything for years and deer don't notice me at all. I now use Realtree AP HD and I still don't get noticed. The goal is to break up your outline and most any camo does that.
But I still want to look good.
