That lets you get even more accuracy from your gun. Another way that etched-glass reticles are superior to wire reticles is when they're illuminated. The etched ones show the illumination only on the reticle. It looks like the reticle is floating. Wire reticles often have a reflection of the illumination in the objective lens, which can be distracting when shooting.
