Depends.
On target guns, scopes are what I want.
On "use" guns, I insist on irons, even if I have a scope.
My eyes suck, I'll be honest, but I can still hit the kill zone of a deer at 200 meters. It's not hard, but you do need to practice (you need to practice with a scope, too, don't let anyone kid you).
It also depends on the irons. I really like the iron sights on my Mosin Nagants. It's a wide front post surrounded by a circular hood, and a notch rear sight wider than the front post. They are much quicker to pick up than Mauser irons, and get the job done well. With the trajectory of the rounds I use, I zero at 200 meters, and I will be 2" high at 100 meters and 3" low at 250 meters. So, out to 250 meters, I just hold dead on and will put the round through the kill zone of a deer/hog with no problem. However, my longest shot on deer was 112 lased yards.
For close-in, I use the front sight hood as the aimpoint (pun intended). The front post is nearly cetered in the circle. I find I can snapshoot by quickly mounting the rifle and centering the target in the circle. The rear sight will be nearly centered properly because of the mount, and at less than 50 yards, I can kill-zone a hog/deer very quickly. My closest kill was 22 yards on a moving hog. Dropped him like a hammer with this technique. At such ranges with snapshooting anything but a large aperture red dot type scope will be a detriment.
Now personally, I don't like "scout" scopes. They block too much of my field of view for close-in shots, and aren't set up well for long range shots. YMMV
You might wantt o try replacing the rear sight leaf with one of the replacement sights (Mojo) that gives you an aperture. It might make it easier to pick up the sights. It's a drop-in replacement AFAIK, so you don't have to permanently alter the gun to give it a try.
