I like both. If I can be so bold as to post my pros and cons of each. I think that there is no right or wrong answer. Both of these optics are tough as hell, I've seen videos of both being run over, dropped, smashed and keep on ticking.
Eotech pros-
-Generally cheaper than aimpoints
-Larger sight window for fast aquisitions and better co-witnessing iron sights
-More modesl to choose from to adapt to different battery types
-I find the circle and dot to be faster aquisition than just a dot. I also enjoy having a 1 moa dot vs a 2 or 4 moa as are on most aimpoints.
Cons
-Slightly less "tough" than aimpoints, though I've seen many destruction videos and it takes ALOT to hurt one of these suckers
-Less battery life than an aimpoint (still impressive though)
-When its raining heavily, the window is more suceptable to getting wet or foggy
Aimpoint pros
-Arguably slightly tougher than eotech. Probably due to farther recessed glass and a more robust "tight" construction
-Ridiculously long battery life
-Less prone to water/rain interfering in glass, though the eotech would be easier to clean
Cons
-More expensive
-Smaller sight window, slightly slower aquisitions
-I prefer the circle and dot vs just the dot. I'd rather have a 1 moa dot rather than 2 or 4.
