What, are you trying to start another never ending debate like the CS vs. FP or TW vs. NW or Tip-up vs. Slider...?
Do a quick search on the subject and you will find a bunch of threads on the subject.
The current debate is the type of light to use more than anything.
The consensus seems to be that the leading edge lights illuminate in front of the aircraft more. Whereas the wing tip lights are very focused out on the wings.
FWIW, I went with the leading edge lights because they will be easier to upgrade once LED's are available at a reasonable price/performance point. Even thought I think the wingtip lights look cool, I went with easy upgrade and better light dispersion pattern over aesthetics.
