I prefer any sight that I can see
Seriously, I like the Glock sights. They just seem quicker for me. As my eyes age I am thinking about getting a fiber optic front sight but leaving the rear sight stock. I don't like night sights because they are hard for me to pick up as easily in bright light. Unless we are talking contact distance, I want to use my sights and to do that I want them easy to be seen.
For target shooting the black on black works fine.
