Personally I prefer the holographic EOTech reticle over the AimPoint's red dot for the advantages of the two eye open shooting method and the fact that no matter what angle your viewing it from (within reason) the EOTech is always on target. That allows for more adaptive shooting positions.
The EOTech's 65 MOA ring allows for ultra fast visual acquisition of the reticle for ultra close targets and the 1 MOA dot allows for very accurate shots even from 100 yards. (I can hit an orange egg no problem, benched, using the single eye method)
EOTech's will drain way more juice because of the complexity of the technology being used. L3 usually makes things like holographic heads up displays for fighter jets so the value in the somewhat 'borrowed from another industry' technology your getting for $400 is exceptionally well priced in my opinion.
Just some of my thoughts, keep in mind some prefer Trijicon, Elcan, Aimpoint, Burris, C-More, SightDoctor etc... There is a lot of options out there and they all have different advantages like weight, price, size, battery life/type, durability, warranty etc. So read a lot of reviews on that particular model before committing to a purchase.
