The more you use iron sights, the less you think about it. Eventually they line up really fast on their own without you actively thinking about it. A reflex sight is a bit faster, but its not going to magically make you a better player.

As for their reliability, of course, if you use real optics, they will probably last a while. But most players use cheap china crap that breaks really fast... and have crazy parallax. I like iron sights a lot better than cheap optics. I also don't want to put something on my gun that is more expensive than the gun itself, so no real steel optics here.

Also, iron sights don't fog in autumn rain.
