they contrast each other perfectly
Ra Ghul or whatever it's not a fascinating enough character, he is too one dimensional because we understand too easily his warped reason for revenge
Bane also (depending on film or comic version) is relatively one dimensional or in the case of the film a not directly menacing villain b/c he did not act on his own accord
Joker is just the most interesting villain and the most different from Batman
The twist at the end regarding Bane's motivations really undermined him as a character, I feel. Up to that point, he was the perfect villain - menacing, imposing, ruthless, destructive. Too bad about the twist.
That said, I'd pick him over the Joker, though it's hard to compare because they are both such different and opposite villains. Still, the fight scene in the sewers is the best action scene in the entire trilogy and one of my favourite scenes from any movie of all-time for how raw and how brutal it is (the lack of music also adds to the atmosphere) and you get the sense that Batman has truly met his match, which doesn't quite come across with the Joker.
The Liam Neeson character was a bit boring. Batman Begins wasn't about the antagonists anyway; in fact, I'd say that the biggest antagonist that Batman faced in that film was himself.
