It all depends on the intended application
When answering these kinds of questions, most people automatically (or unconciously) focus on duty style or defensive handguns. And for them, IMHO, it still depends, on who is holding the gun.
I prefer the single action trigger. I don't mind the DA/SA style, but I wouldn't want one on my .22 plinker. I'm fine with the SA on the 1911A1, for me, but I don't know about you.
For guns that are intended for police duty, I think a light crisp SA trigger is unwise. Because police hold people at gunpoint frequently, I think something more "forgiving" such as a DA/SA, DAO type is safer.
Range shooting, plinking, hunting, a light, crisp SA trigger is the way to go. High stress, "combat" situations? No. Not the best idea, for the majority of people.
