I'd get SA/DA;

only the
first shot that will be ligher (SA trigger pull of a SA/DA is lighter than DAK trigger) plus if you rack the slide (to load the gun) the trigger will always be in SA
This sounds like good advice to me. The SIG catalog lists the pull on the P226R SA/DA as 4.4/10 lbs. For the P226R DAK it is 6.5 lbs. So the SA is the lightest of the bunch.
From what I understand, the DAK trigger was developed for law enforcement. All LE carry a round in the chamber, but not a round in the chamber with the gun cocked in SA. You might try that with a USP (with the safety on), but with a SIG you are going to have people shooting themselves in the leg. So departments that carried SA/DA guns (like SIGs and Berettas, for example) put their oficers in the position of having that dreaded long, hard (and often times way off the mark) first shot in DA, with subsequent shots in SA. So you have the double problem of a long DA pull followed up by a totally different SA pull.
So, the DAK trigger takes the benefits (reliability, accuracy) of the P226 pistol and makes it more effective for law enforcement purposes by making it simpler - no de-cocker, bobbed hammer, same trigger pull on every shot, and can be carried safely without a 10 pound pull on the first shot.
The guys that like the DAK are people that are training for carry purposes, or other self defence application, or guys that already have lots of time on SA/DA guns and want to try something different. Both the DAK and the LEM (Law Enforcement Modification) for USP pistols are both highly regarded as being very smooth DAO triggers, and many people seem to find them to be far superior to Glock triggers.
My 2 cents worth, if you are a new-ish shooter wanting to build up your accuracy on stationary targets - go for SA/DA all the way. If you are carrying your gun around Utah, or you are practising for the next Huricane Katrina, have some other reason for needing a gun with a round in the chamber, or if you are just wanting to try something different - go for the DAK.
