Budget plays a huge role in picking "what's best." Additionally, the best flashlight for the outdoors won't necessarily be the best flashlight for general use around your house and workplace (depending on what those environments are, of course). I've used small Streamlight handhelds that work great for EDC, Surefire handhelds that can double (almost) as hammers, and currently carry a Cloud Defensive handheld that can really punch light out a good ways. It's great for spotting small predators in the treelines at night when I take my dog out (we've had a lot of foxes pop up recently, and while we're not worried about the garden variety fox, if I can avoid them, it's better).
