Wow, this is a difficult question and one that I think will vary greatly from person to person for a wide variety of reasons.
1) TDKR - this had all the entertainment value and awesomeness of the first two but with the added awesomeness of Tom Hardy's performance as Bane (and, no, I wasn't a Hardy fan before TDKR).
2) TDK just squeaks past BB because of Ledger's performance, though it's damn hard to beat Liam Neeson (oh, how I loved his cameo in TDKR).
3) BB - when I think of other "superhero" movies, nothing can compare to BB; truly ground-breaking.
