Get the Aimpoint. It is that much better...
I have had both! AimPoint is a MUCH better optic in my opinion....the Eotec had a fuzzy reticle and shorter battery life...the Aimpoint has a MUCH longer battery life and a much cleaner and clearer reticle that I like MUCH better....for the money it is hard to beat an AimPoint...
For the money, take a look at the AimPoint PRO...great optic.
I use one on my 107CR and love it!

... that any other shooter won't need to consider. The only question after battery life and waterproofing is the reticle...that's a personal choice and is way to arbitrary for anyone to say that "it's this one...or that one." Note: The Eotechs are super tough, I have yet to break one from dropping it or banging it. They just aren't quite as meticulously engineered to be run hard and long in the outdoors with no battery changes or to be submerged in water.
