One other thing about the EOTech (and the Aimpoint and other red dot sights): I have found that, outdoors in very bright sunlight, you can lose the reticle even if it's on full. I was surprised to discover this, but living in Florida made this apparent very quickly.

The reticle of an ACOG switches its contrast in real-time to always be visible against whatever the background is. It's always there.

Just my own observation, but I note that in theaters such as Iraq, the guys with the EOTechs and Aimpoints are in the urban/suburban areas, and the guys with ACOGs are out in the open field. Perhaps this is the reason.

The ACOG is also magnified, whereas the EOTech and Aimpoint aren’t (unless you get the $500 3x magnifier).

My TA31RCO-A4 is mounted on my 20 inch model AR-15. I have the EOTech 552 XR308 on my AR-10 rifle. Sprang for the EOTech 4x magnifier for that one as well. My M-4gery sports the Aimpoint M2, with the 3x available when I need it.

The ACOG is my favorite, but I need to get a Docter red dot to mount on top for closer in shots.

Pretty much can’t go wrong with any of them. Expensive? Yes. But I wouldn’t trust my life with any of the cheaper stuff.

Well, the ACOG is also 4X, so it makes more sense in open country for that reason also.
