I can't say I like the EOTech better, I have never had a FF. I didn't like the sight removal to change battery on FFII and was not patient enough to wait on FFIII availability to put on my latest gun. EOTech was, in my opinion, best option for me at that point. I really like what I see out of the FFIII and would not rule out trying one at a later date if I have need. I do like my EOTech though and am happy with my decision. I think they are both quality sights, just depends on what you want/need.
