What kind of optic you want depends on what kind of shooting you plan on doing.
Nothing is faster up close than a 1x reflex sight, like your EoTech. The 1x is usable out to 250-300 yards, depending on how big of targets you shoot. What the 1x optics aren't is precision sights for seeing how many holes you can make touch on a bullseye.
Magnified scopes let you see what you're shooting better but at the cost of being slower to get hits very close up, requiring you to have your eye placed very precisely behind the optic, and limiting your field of view. The higher the magnification, the worse these problems become.
Considering most people can't find targets or don't have access to ranges that are longer than 300-400 yards, personally I find anything over about 6x to be overkill. My own magnified optics are 3.5x and 4x, which, for me, hits the sweet spot of being able to acquire targets, have a decent eye relief and field of view, and have a decent sized exit pupil.
