I would take the DW for a couple reasons, the first being that I can actually work on it myself, and fix any conceivable problem it could have with the parts I have built up over the years. The design is so much more simple, and to me, logical, than the S&W mechanism. The second being I just like the DA trigger better than the 586/686. I currently have 3 DW .357's, a 6" near mint 715, and nice shape 4" and 6" Model 15-2s. All are VH barreled. I also have a 6" VH Model .44. I paid less for any two of the .357's than a decent 586 would probably go for. All four guns cost less than $1300, shipped and transferred.
