I have worn both and I personally prefer the Defender. There were a few different things that make me like it better. I like the fact that the angle of the device is adjustable on the Defender (important if you drive different types of cars) I also personally felt more comfortable in the defender vrs the hans ( I am a big guy and it just fit me better) and lastly the cost was very attractive, though this should never be a reason to select safety equipment, but this is the real world and its a whole lot easier to swallow the lower cost of it compared to some of the others.
