I've been giving this issue some serious thought on why it seems off to me. From even before the start of this relationship Superman has always seemed to have a crush on Wonder Woman, look at every panel they are in together, he is just staring at her like he can't believe she's real. He looks at her like people look at him. I imagine that when they kissed He'd go bouncing around like a freaking Loony Toon cause that's how much he was gone for her. This is a Different Superman, he just is. He parents were different, his mom was a soldier not a scientist or laborer in this reality. He has aggression in his DNA. The Kents were different, Pete's different, Lana's different, Everyone is different. Why can't his love be different too? Yes Diana's the Goddess of War now but Ares loved the Goddess of Love, Why can't War embrace Hope now?
