Optics on rifles get you hits faster than irons.
Optics don't get you hits
at all. They
can facilitate quick hits by a shooter with a lot of practice. I'm not entirely sure about initial hits. And I think gun fit matters more.
To an extent, these are short-range applications. The shooter who can get the gun up to his shoulder, point and shoot somewhere near center-mass the fastest has the advantage. It seems that few people practice this. If you do, more power to ya.
If you think that optics really matter, instead of gun fit, "pointability", and practice, in this scenario, try bird hunting sometime. Or try hitting hand-thrown clays with your rifle. It can be done (with a proper backstop). Cheek weld, body movement, and the way the gun handles all matter. The sights, whatever they are, are only used subconsciously. If you don't move with the gun, and if the gun doesn't naturally move with you, optics won't be all that fast, either.
So sure, optics are great. But at HD ranges, the
optics don't hit the target, fast or any other way. You do.
Now at 150 yards in twilight, of course a good scope is going to work a lot better than irons. My home, however, isn't that big.
