Not a Miller fan by any stretch but The Mazzuchelli one is closest to what I would like to see on screen. I think it has a kind of natural look that is both more dynamic and less forced than the heavy gobs of armor. It's amazing, like he gave the Adam West suit a few key tweaks that were able to make it look totally as cool as it needed to be. Yeah, yeah I know. West equals camp, EVIL! But go with me on this one for a second. I'm not advocating the Bat-Tusi here.
I really wish they had the balls to attempt the white eyeslits. Maybe take that design only use a dark blue material kinda like West had only have him in shadow or have it be black but backlit in blue to give that classic highlight ala the comics and Bruce Timm art. But don't use yellow for the utility belt though. Either have it be a kaki or grey color. Possibly make it a gold and metallic like the Ross belt but keep the packs and everything about that same size. I think tne problem with the Ross belt is since it's so large it makes his Batman look unintentionally fat.
