Very very late, but I think I have some ideas to answer this question.
"I don't wear hokey pads" scene is one of my favorites, a great way of showing Batman enter the scene to remind us it's his movie, and some of the influence he has on the city.
Courthouse scene with Sal Maroni and his canon fodder on the witness stand is overlooked as one of the highlights of the movie.
"You either die a hero, or you live long enough to see yourself become the villain". One of the most remembered and quoted lines from the movie, a meme generator, and a good way to introduce Bruce Wayne and Harvey Dent to one another.
Lucius Fox deserves to be one of the more iconic characters in the movie, all the assist he gives his boss represent greatness in character, talking to the accountant trying to blackmail him is one of the underrated gems of the film.
"I believe in Harvey Dent", Rachel's doubt in Bruce, and the entire scene is amazing and heartwarming. I'm talking about the penthouse scene before Joker barges in.
List as many scenes as you will from Batman Forever that outshine these moments from TDK.
