Ledger joker isn't an anarchist, he's not out to overthrow the government because he believes that people don't need it and can govern themselves. It's the exact opposite in fact he believes people, their beliefs and moral codes have no value by default and he works to proof that by attacking civilized society. He's a Nihilist really.
Jared Leto's joke hasn't been seen in full yet to make a judgement. He could be a psychopath type or fail to achieve this and come across as a joker fanboy more than the real deal.
The remaining two I'll agree with.
