I’ve always believed, sights (grips too) are all a matter of preference. What works for me, may not work for you. So there is no right or wrong answer.
Find out what works for you. In fixed sights, I need a bold front sight with blank, black rear. As I age, I anticipate needing to use my red dot sighted guns more- I am resisting it, but recognize it can be an aid to my speed and accuracy.
