Absolute Co-Witness or Lower 1/3 Co-Witness?

Absolute co-witness means that red dot sight and iron sight align with each other. The iron sight and the center dot are at the center of the window.

Pros: It allows quick target acquisition.
Cons: It obstructs part of your view.

Lower 1/3 co-witness means the red dot sight is settled over the iron sight. The iron sight is at the 1/3 of the window. Two kinds of lower 1/3 co-witness, the dot at the center of the window or the dot at the center of the iron sight. 

Pros: It provides wider view, compared to absolute co-witness.
Cons: You will need to adjust the line of sight when switching between the red dot sight and iron sight.
