Reference Red Dots, I am slightly quicker when it comes to target discrimination drills with my Eotech than Aimpoint. Both are outstanding optics and are in use overseas in combat. I find that the "halo" of the Eotech allows me to quickly identify whether or not the specific target I am shooting is within the correct parameters before squeezing off. This is particularly helpful when transitioning laterally from target to target where shots count (HP/LP for example). For me personally I find that method easier than trying to center the single red dot of the Aimpoint (although I can do that as well, just not as fast).
It's all up to personal preference. I say try a few options and see what you like best. Good luck with your purchase.
