I own or have owned about all the DW 1911s mentioned in this thread. DW quality is the best you can get in production 1911s without jumping to semi-customs. I have the ECPs in both 9mm and .45acp. I am not a fan of CCOs although I have owned and shot several. In commander size, the ECPs have been my favorites because of two things. Balance and recoil. These are judgement issues for each person but for me the ECPs balance better than any of the 4.25 commanders that I have shot. They just feel "perfect" in my hand. Also for some strange reason the perceived recoil seems to be minimal even with the lightweight frame.
I'm not too crazy about the gold bead front sight. Some folks like it but to me it seems to blend in with the sight body, and doesn't present a clear distinct appearance. Not much to gripe about, may change it someday to a FO.
