Cody, I built a queen size custom bed for a lady last summer, and I found that the hook-type (example #1) is excellent except that it's a bear to install. They have the same types of hooks & bars that are a flush fit ... that's what I used. You just route out a mortise deep enough to accommodate the hardware. It was simple to install, and it fit so tightly there will never be a squeak. Ever. I think I paid about $3 each at Ace Hardware (here we have something called Elliott Ace Hardware, which carries everything). My logic was simple: I wanted it easy to do, strong, no squeaks, and cheap.
