No amount of magnification is good for close quarters/home defense. Even if you train with it a ton, you don't want to spend compute cycles working out magnification in a stressful scenario. Any of the quality 1x optics, like Aimpoints, are going to be a much better option. Throw a 50 yard zero on it and you are good from 0-200 yards without a lot of thought or effort. I used to own a 1.5X ACOG and the clarity was great and it was fun to shoot at the range, but I sold it and would never get another.
ACOGs make a lot of sense as a battle optic when you expect a longer engagement distance. They really simplify training folks to accurately hit at extended distances, and they are durable AF. The quality of more traditional riflescopes has improved, allowing much more versatility than a fixed magnification range. So, in this price range, most folks would pick something like a 1-6X Vortex Razor. But most of us would still tell you that is a terrible choice for home defense, because even in that case, "1x" is still with an aperture a foot or more in front of where your eye is, which can make things slower to see/understand than using an unmagnified optic, like an Aimpoint or Eotech. The reason many of us recommend Aimpoint for home defense is that they have great quality and a battery life measured in years.
