I think it's the Mets. They swept the Yankees recently, and almost swept the Braves in a five games series.
The Mets have the TWO best active pitchers in the League now, but the Dodgers have more depth at Pitcher. Well, DaGrom had a perfect game bid yesterday, but blew it in the sixth inning. He was understandably pissed at himself too. Anytime you're that good at something, you're addicted to winning.
