Iron Man by a long shot. IM gave you the Marvel comic book experience. You could follow it and had a sense of the characters portrayed. They each had a distinct configuration of strengths. Through them the viewer could experience moments of suspense, hope, and triumph.
I found the entire TDK movie to be brutal, almost sadistic. I am not just referring to the Joker. I never identified with the characters. They simply functioned to carry out the moves in the plot, like chess pieces, with the exception of the sociopathic Joker who had some substance, albeit a pretty bizarre "victim." The last 2/3's of TDK had way too many disorienting scenes, sonar vision, chases, fights with odd editing and impossibly loud punches, etc. I was relieved when it finally ended. IMO TDK is waaaay over hyped.
