This is strictlly personal preference. I am fairly certain my opinion is in the minority but I will share it with you anyway. I have always been a big fan of DAO for carry purposes. I know there is nothing that feels as nice as a custom SA trigger on a 1911 (BTDT), but I just don't like the added "issues" of carrying SA pistols. Especially if it isn't possible to train with it regularly.
My quest for the perfect carry weapon went like this:
The first gun I carried was a Colt Gov't Model 1911. Wonderful pistol and I am a huge fan of the 1911. I just never liked carrying "cocked and locked". You also add a step in deploying the weapon with the need to disengage the manual safety.
My next pistol I carried was a Sigma. A DAO, striker fired pistol in .40 S&W. I liked the DAO aspect with no manual safeties, but I hated the trigger.
I replaced the Sigma with a Para Carry LDA. In this pistol I kept the DAO which I liked but got the manual safety back. The LDA trigger was nice in that it was DAO, but it still wasn't what I was looking for.
I now carry a Sig 229DAK. This is by far the best CC pistol I have ever had the pleasure of using. The DAK trigger is great. Just like the camera, "point and shoot". DAO, no manual safety, and repeat strike capability if you want it. It also doesn't hurt that the pistol's accuracy and reliability are very impressive. It will shoot anything I put in it and I have cut ragged holes at 12 yards (and I am not a very good pistol shooter). To say I am pleased is an understatement.
In the end, what trigger you pick is usually just a matter of "what works best for you". If you are already more familiar to one type or the other, stick with what you know and are comfortable with. If this is your first serious venture into shooting, then I would recommend the DAK, but then I am biased.
