I can't say one brand over another, but I do have a criteria for wilderness lighting, it goes like this...
I want a light that I can see well enough to walk on the darkest night. I want it to have at least 16 hours of runtime, so at least 2 nights of continuos light. It has to be less than 8 ounces and take cheap batteries, like AA. It must be reasonably waterproof, hold up in a heavy rainstorm.
I always carry spare batteries and bulbs, if not an LED.
Oh, one other thing, it will always be a headlight, that way I can use it hands free or in hand.
I carry a spare LED mini light as well, always!
