Viper HD 2-10x42 vs Fullfield 2.5-10x42 - Two Scopes Enter One Scope Leaves.

In this review and comparison we are looking at the Vortex Viper HD 2-10x42mm with the illuminated Dead-Hold BDC reticle and the Burris Fullfield 2.5-10x42mm with the Wind MOA reticle. Both of these were bought with the intention of replacing the scope on my Ruger American and now I have to decide which one is remain, and which one has to go.
