I used to have a Copper John, but sold it in favor of the Sniper. I personally feel the pins are a bit more protected in the Sniper and the adjustments are nicer on it. Plus, the light on the Sniper shines away from the deer toward you, but is blocked from you vision. Pretty neat.

I don't think you can go wrong with either one honestly though. Both are extremely well built, I just happen to give the nod to the Sniper.
