Sleeper is the best from all you have mentioned. And it's best Brubaker, no doubt about it.
Second place: Gotham Central, really good stuff, procedural police work.
Third: DD by Bru. His Marvel stuff is ok, but it's Marvel and they don't do much good books, personally I would avoid Marvel as much as I can but they have published couple great books, like Elektra by Miller, or my fav Punisher Max by Ennis.
