Snyder for me. I do not like Morrison as a writer or as a person. New X-Men, Cassandra Nova, changing Beast's appearance, publicity stated that Batman is gay, having Joker imply that there is a homosexual relationship, and because of the age difference you know what else this implies, between Batman and Robin in Arkham Asylum: Serious House/Serious Earth and the list goes on. All of this is from Morrison.
Morrison gave us Damian Wayne so he wins.
By taking an idea from an Elseworld story that he did not even read.
Well Snyder has basically been implying that there is a homosexual relationship between Bats and Joker too.
