I sometimes night hike, particularly in winter, and for those times when I really need to see where the trail grows as it becomes faint or confusing, the Eos is the hands down winner.
The Scout is more of a neat toy than a headlamp I could nighthike with, though it is OK for camp chores and the like. The sheer cost of its batteries prevents me from using it very often while backpacking, but it lives in the pack I carry to and from work all the time.
The Tikkas are decent, but because they are unregulated, I often found that while they were OK while in camp, then if I needed to shine it into the darkness to identify a strange sound or night hike, the light was so dim it was almost unusable. Better than nothing, but no contest versus the reliability of the PT Eos.
