that is certainly a matter of opinion, but, at the risk of overgeneralizing, many will say something like...
some of the other systems might be faster to get on target...but possibly at the cost of some accuracy. however, for self-defense/combat purposes at close range, you only need so much accuracy--faster on target can be much more important.
some of the theories behind various sights i have heard are things like:
-it is faster to line up two things (be they both dots or a dot and a line or whatever) rather than three
-a three dot system requires precisely lining up the dots in both the vertical and horizontal planes--but people are much taller than they are wide and the effective COM target area is taller than it is wide. a dot-the-i or two vertical dots system takes advantage of this by allowing you to focus more on a precise horizontal alighment while not worrying so much about a precise vertical alignment when you are trying to go fast.
-the V in the back sort of guides your eye to the front sight
-the big dots are easier to see and, thus to pick up quickly, under stress
i have used sight systems other than 3 dots, but only for a few shots here and there on other people's guns, so i can't really comment on the realities of other sight systems.
i do think some of the theories make a lot of sense--and a lot of very good shooters use other than 3 dot systems. someday i will likely give them a try, but, i find myself having a hard time letting go of the 3 dot system i am used to.
