Ditto on the preference of the cool white over the natural white. I have several flashlight in both the regular and natural white with the SST-50 emitter. The difference is 100 lumen but the color of the light sure looks a lot more than the 100 lumen difference. I think the eyes can perceive the regular cool white tone much better than the natural white tone when using these flashlight out on the road. The difference of those two flashlight you chosed might only be 15 lumens on paper but may actually be more because of how your eyes and brain defines the color difference.
I took all my natural white flashlight and use them as regular flashlight at home and work because I did find them useful in close quarter where they will not be glaring back at me when I am shining them on a glossy painted surface.
