Yep. Dr. Strange used his intelligence instead of his Mother.
Dormammu, I've come to bargain!

Agreed. Doctor Strange hands down.

Because the Joker put all of his eggs into the wrong basket. His final scheme was based on his earlier hypothesis that, when the chips were down, "these 'civilized' people..they'll eat each other." He resigned to Batman's brute force approach because he figured he had won the chess match, and the people on the boats were still going to blow each other up. He was wrong.
In the case of causing Batman to kill Dent, I think that part was situational. Joker didn't create some scenario where Batman just flew into a rage and murdered someone. He made a split-second move, to save a child's life, and couldn't do so without knocking the three of them out of a window. Dent simply wasn't able to stop himself from falling.
But, yeah. The Joker was wrong about the people in the city, and that trap he'd set was his grand plan. It was a dud.

That's a first. What makes you say that?

I see it as Joker defeating himself.

For me it's The Dark Knight, even though I see it as Joker defeating the Batman

But that doesn't answer the question at all

If the DCEU can figure out how to get rid of Zack Snyder, they'd win this one hands down.
