I know that this doesn't help, but you have to try both and see which one works better for you. An Aimpoint is pretty vanilla and anyone can get used to using it. However, the EOTech is a much more advanced optic. To those who haven't taken the time to really get used to it, it seems bulky, overly complicated, and seems to have a busy sight picture. However, if you give it a chance, it operates just as quickly through its tactile interface and the reticle is much faster in close target acquisitions. The smaller center dot is useful for long range shots as well. The large circle draws your eyes to the reticle and you can then focus on the center aiming dot if you need to. It sounds like a slow process, but is actually very, very fast.
Obviously, I am an EOTech fan. It works for me. As far as price goes, the last time I checked, the prices for the two were the same, exactly the same give or take a whopping five dollars either way. The aimpoint is the safer choice, but I feel the EOTech is more advanced and offers a better package in general and offer better advantages for those that know how to use them. However, everyone is different, and what works for one will not work for the next. If you can, try both. Or jump straight to an ACOG. Hell, just get all three. Eventually you will want to anyway.
