Which hacker conference is better

Next year I was planning on going to Defcon. I am more interested in physical security than IT security. Probably since in my past job I did allot of application hacks for banks and different corporations. My current hobby is lockpicking. After looking at the Fifth Hope Conference website. This conference looks like it may be the one to go to. Has anyone been to both of them? Which would you go to if you could only do one?
