If you have FOV issues you are doing it wrong
FOV is probably the wrong term. The Eotech offers a larger window in which to find the reticle, making eye-to-sight alignment less critical and hence making pickup slightly faster, in theory.
The Eotech also offers a much sharper dot, which is an issue
if you plan to run a magnifier. (The Eotech dot is far smaller than the diffraction limit of the human eye, so that it looks like a ~1 MOA dot unmagnified, but 1/3 MOA under 3X magnification, 1/4 MOA under 4X, and so on until you reach the diffraction limit of the magnifier or of the optic itself (smaller than 1/4 MOA). The Eotech also offers a reticle rather than a simple dot, which is good or bad depending on your personal preference. (I personally prefer a newer model Eotech over an Aimpoint, but to each their own; they are both good optics.)
The Aimpoint offers longer battery life, may be slightly more durable and impact-resistant (though comparing early battery-contact-plagued Eotechs to modern Aimpoints is an apples-and-oranges comparison, compare current production to current production for meaningful data), and is much easier and cheaper to fit with flip-up covers to keep the lenses clean.
As to the OP's question, I believe the Eotech is the only
holographic sight currently on the market, though I may be wrong. Not all red dots are holographic (most aren't), and AFAIK none of the cheap Eotech knockoffs other than the discontinued Bushnell are holographic.
