I won't go into the pros and cons, I'll just stick with my situation.
At some point in my life, the front sight started to get fuzzy. I started wearing multi distance glasses, not much help for shooting. Then, it got harder and harder to shoot.
Lasik surgery helped a whole lot. But, add more years, and the front sight started getting fuzzy again. My reading glasses helped, but then the target was fuzzy. Walking around with reading glasses would be a problem. Now, at 75 years old, it is a real problem see the sight without them. I don't need multi vision glasses, but I do need help to read and see the sight.
With red dots, the dot and target are in the same focal plain. I also get the benefit of now shooting with both eyes. That was something I was never able to do. It took some work to learn, but I was able to shoot again.
Yes, there is that pesky stigmatism, but it's not too bad. A 3 MOA dot looks like a 6 MOA dot. It works for me.
I don't tell anyone they should be using a red dot, that's their decision. But, the red dot lets me shoot again.
We are all different. It's a big mistake to expect us all to be alike. Some like red dots, some don't.
