There's something to love about each one. I'll have the Tumbler soon which will be my fifth but I'll not get them all due to personal preference or attachment to the medium. So far, my disappointment is the Arkham Knight: it's missing fins and specific details that are keys to the design. The biggest surprise was the Animated Series due to the sleek, blocky design that is preserved near perfectly. I love the 89 (I got the large LEGO set) for being THE gold standard and the Reeves' version due to the callback to real vehicles and how all of this was engineered during what was possibly the worst timing imaginable.
