The guys at RangeTime do a comparison of Aimpoints and EOTechs.

It’s a fairly simple issue for me. Either are great, but if you are more interested in battery life, go with the Aimpoint. If you are interested in more precision shooting, the EOTECH’s 1 MOA center dot allows a slight bit more precision than the 2 MOA or 4MOA dots on the Aimpoints.

That allowed, I use neither. I find that for my purposes, a low variable power scope works best. To each his (or her) own!
