Holographic sights like the 551 have an advantage over regular red dot sights because they are near immune to parallax distortion. With a red dot sight your eye needs to be in line with the sight so that the reticle will be lined up with the target. If your eye is not lined up, your shot will end up being off target. With a holographic sight, you can move your eye off the sight line, and the reticle will stay on target. This has to do with the way the reticle is projected onto the lens and is why holographic sights are more expensive, and superior, to basic red dot sights.
