Both projectors offer really good shadow detail, but the InFocus seems to have a slight advantage. You can see just a touch more detail in the shrubs on the far right behind the train tracks. Remembering that a simple adjustment of +1 (or -1) to brightness, can make a difference this slight. In other words, while the InFocus looks a touch better, that may not be the case if someone else sets up and calibrates. I'd call these pretty much a tie. That is, don't worry about shadow detail.
A few additional images from each projector: First, three side by side images from The Dark Knight, and one from Space Cowboys.
