Here is Quentin's statement from Collider:
“It’s The Social Network, hands down,” Tarantino said. “It is Number 1 because it’s the best, that’s all! It crushes all the competition.”
His second choice is Dunkirk which was directed by Christopher Nolan.
“The first time I saw it, I don’t know what I was thinking the first time. I just dealt with the spectacle of it... It wasn’t until the third time that I could see past the spectacle and into the people the story is about,” he explained, adding that it jumped from seventh on his list to second.
