i went with the vortex because, when i compared them side to side the vortex gathered way more light, and the glass seemed clearer. at about 5-600 less than the vx3, i was able to buy the sunshade, anti cant level, leupold rings and bases, pachmayre f990 recoil pad, and still came in 300 less than i would have with the leupold. as soon as i get the scope in my hands im gonna go have bass pro mount it.
