of course the surefire's have better build quality -- but at more than double the price. even at $50, the Fenix is beyond what a lot of people will spend for a flashlight, but I am impressed with both models. And I like my surefire's too, but I spent a lot more for them. and the surefire will still be edc, since led's are not that great in a smoky environment [ a fire for instance] from what I've read in different forums. the surefire is apparently a stronger beam for those type situations.
