Z brackets for picture hanging - secure, aluminum, and way stronger than magnets.
I actually prefer the Z brackets to magnets myself, that or a french cleat, basically same principle.
Magnets have their uses, but they don't line anything up perfectly, a guide of some kind may be needed if you need it perfectly straight or level, sometimes it's a pain to get them secured w/out popping out or off, and of course you have to be very careful to not go through the face of your door if you are using something like a paddle bit that has a deep pilot/point.
Often people end up putting a cleat down below to guide and carry the weight properly.
