All depends on $$, fit, and intended use.
For target shooting, eg PPC, a DA\SA will give you a different trigger pull between first and subsequent shots,,, on the other hand, decockers are sure nice to have.
Trigger pull - (I have Walther P99, and a couple of CZ's), but if I could find a gun that fit in the rules, I'd have a Para LDA in a heartbeat (closest thing to a revolver I've experienced)
For accuracy, relatively small $$, and simplicity... CZ 85 Combat or CZ 75 (need to decide between adjustable sights, or decocker,,, OR put adjustable sights on a CZ 75B. Want to spend more $$$,, lots of choices,, S&W M&P is also very nice, and built like a Mack truck..
IMHO...
