On the range with no one shooting back dao or da/sa is just a matter of concentration on the task at hand.
When your desperately trying to deploy your firearm against a goblin intent on killing you.... its almost impossible to land hits where you want. More a matter of luck than anything. Its why i carry a xdm or 1911. Both are single action. There us no need for the trigger to cock the firing pin like in a dao, dasa, revolver, glock, m&p. Its the same trigger pull everytime.
Im not saying you cant use them effectively but eliminating as much monkey business as you can between getting a round centermass may mean the difference between life or death. I carry an xdm over a 1911 because the there is only a grip safety on the xdm. All i gotta do is point and shoot. Trigger pull is the same light pull everytime no stacking or mushiness.
For pure target shooting it takes a LOT of effort for a 1911 to get anywhere near the crispness that can be produced in a revolver single action trigger. Sig has a target version of the p226 that is simply mind blowing in single action.
Anyway those are my thoughts take em for what any interweb opinion is worth.
