"Arguably, the two most popular holographic sights on the market are the Aimpoint Comp and the EOTech.
Price: The EOTech can be had from about $175 (if you get the Bushnell version which lacks some bells and whistles) to $400. The Aimpoint can be had starting at $329 up to $450. The EOTech comes with a mount. With the Aimpoint, plan on dropping another $80 to $150 on a mount. Advantage: EOTech.
Battery life: EOTech from 200 to 1,100 hours. Aimpoint: 12,000 to 50,000 hours. Advantage: Aimpoint.
Ergonomics: The Aimpoint’s controls are twist knobs. The EOTech is push-button friendly. The Aimpoint is more like a rifle scope in feel whereas the EOTech is like a fighter jet targeting system. Advantage: Draw.
Reticle: Aimpoint has a 2 or 4 MOA red dot. The EOTech has a 1 MOA dot inside a 65 MOA circle. The circle can be used for a SWAG of range finding since it’s about the size of a man at 100 yards. Also, the large circle is adequate for close applications. Advantage: EOTech.
Glass Breakage: If you break the glass on your Aimpoint, game over. The EOTech will function when the glass is broken. Advantage: EOTech.
Cowitness: Both will cowitness on an AR-15. Only the Aimpoint will cowitness on an AK, if you use an UltiMAK mount. The EOTech with its built in mount sits too high for cowitnessing on the AK. Advantage, Aimpoint because cowitnessing on an AK is huge.
Night vision compatible, brightness, clarity: both come in night vision models, have brightness controls and are crystal clear. Advantage: Draw.
Environment: The Aimpoint functions at lower temperatures than the EOTech. The Aimpoint is submersible to five meters. The EOTech is supposedly waterproof (not sure how that’s defined). Advantage: Draw.
Flash: The Aimpoint dot can be seen from the other side as it projects a dot from the rear. There is a kill flash made for it. The EOTech does not project a light signature. Advantage: EOTech.
Adjustments: EOTech 0.5 MOA per click. Aimpoint 1 MOA per click. Advantage: EOTech.
By a score of 5 -2 - 3, we call it for the EOTech. But it’s a close 5 - 2 -3."
